A Popularity-driven Controller-based Routing and Cooperative Caching for Named Data Networks
NoF 2015

Montreal, Canada, September, 2015
Anglais - 5 p - Abstract
In this work, we investigate cache admission policies and forwarding decisions that account for vontent popularity in order to optimize the named-based routing performances in Named Data Networks (NDN). To achieve this goal, we propose a new controller-based, neighborhood content-aware, popularity-driven routing tightly coupled with a cooperative caching strategy, named Controller-Based Caching and Forwarding Scheme (CCFS). The rationale behind our proposal is to divide the network into domains mastered by cooperative Controllers forming a Connected Dominating Set (CDS). Controllers are responsible for making judicious request forwarding decisions while holding the most popular content requested in their domains. To gauge the effectiveness of our proposal, we conducted extensive simulations. Results show that CCFS reduces the mean hit distance by up to 30% and minimizes the communication cost by up to 47 times in comparison with a prominent existing approach - COntent-driven Bloom filter based Routing Algorithm (COBRA) as well as the default NDN routing. In addition, we observe that the performances of our proposal are very close to those achieved by the Best-route forwarding scheme using location-based Dijkstra's algorithm.

Interference-Aware Game-Based Channel Assignment Algorithm for MR-MC WMNs
Interference-Aware Game-Based Channel Assignment Algorithm for MR-MC WMNs
Bezzina Amira, Ayari Mouna, Langar Rami, Pujolle Guy and Saidane Leila
Rio de Janeiro, Brazil, November, 2014
Anglais - 6 p - Abstract
One of the main challenges of multi-radio multi-channel wireless mesh networks (MR-MC WMNs) is how to efficiently avail from the radio resources available in the network. The level of interference experienced by the mesh nodes rises when the network becomes more connected and the number of radios per node increases. To mitigate interference experienced by the wireless mesh nodes while taking advantage from the multi-channel network aspect, we propose a novel Interference-aware Game based Channel Assignment algorithm, named IGCA. We prove through simulations that our proposed algorithm contributes in alleviating the node interference degree, fairly allocates interfaces to network non-overlapping channels and increases simultaneous transmissions in the network. An improvement up to 50% of both interference degree and simultaneous connections is particularly observed in comparison with a prominent existing approach - the Near-optimal Partially Overlapping Channel Assignment algorithm.

Reducing DDoS Attacks Impact using a Hybrid Cloud-Based Firewalling Architecture
Global Information Infrastructure and Networking Symposium

GIIS 2014 - Toronto,Canada, September, 2014
Anglais - 6 p - Abstract
A Distributed Denial-of-Service attack is an attempt to prevent legitimate users from accessing information or services. In fact, it is a battle of resources between the defender and the attacker. Hence, in order to deal with the denial of services, the proposed mitigation tools are mainly based on the philosophy of Cloud computing which relies on sharing resources. In fact, it offers numerous resources, with high availability and performances. This concept provides us with a new way to cope with DDoS attacks. Cloud computing offered IT resources as services which are more affordable, flexible and attractive to business. Therefore, we present a DDoS attack mitigation service supported by an efficient and hybrid cloud based architecture. It uses the flexibility and the availability of the Cloud, as well as the support of traditional firewalls and intrusion detection systems, to cope with massive unanticipated volumes of traffic in order to improve their performance dynamically and on demand.

Dynamic Coding for TCP Transmission Reliability in Multi-hop Wireless Networks
The 11th IEEE International Symposium on a World of Wireless, Mobile and Multimedia Networks
Vu Thuong Van, Boukhatem Nadia, Nguyen Thi-Mai-Trang and Pujolle Guy
Sydney, June, 2014
Anglais - 6 p - Abstract
Recent research shows that random linear network coding is adapted to current network systems to provide transmission reliability. In lossy wireless networks, TCP traffic has to resist against losses by a suitable network coding scheme and redundancy control. Whenever TCP wants to transmit a packet, the original TCP/NC could send more than one coded packets which combine all non-ACKed packets remained in the TCP congestion window. Packet losses are essentially masked by TCP/NC from the congestion control algorithm. The original TCP/NC lacks an adaptive redundancy control to compensate errors in time. We present Dynamic Coding - DynCod, a new coding scheme, to address this problem. In DynCod, when TCP wants to transmit a packet, DynCod will code this packet with others non-ACKed in TCP congestion window. Therefore, the latest data is always transformed and presented by only one coded packet at a time. Thank to this progressive encoding of DynCod, any decoding failures at destination can be seen as a signal of loss. The source can be informed via TCP ACKs and adjust the number of redundant packets accordingly. We have compared the performances of DynCod and TCP/NC using NS-2. The simulation results show that DynCod outperforms the original TCP/NC in terms of throughput and packet delivery time.

Firewalls are the first defense line for the networking services and applications. With the advent of virtualization and Cloud Computing, the explosive growth of network-based services, investigations have emphasized the limitations of conventional firewalls. However, despite of being impressively significant to improve security, cloud-based firewalling approaches still experience severe performance and reliability issues that can lead to non use of these services by companies. Hence, our work presents an efficient architecture to manage performance and reliability on a hybrid cloud-based firewalling service. Being composed of a physical and a virtual part, the architecture follows an approach that supports and complements basic physical firewall functionalities with virtual ones. The architecture was deployed and experimental results show that the proposed approach improve the computational power of traditional firewall with the support of cloud-based firewalling service.

Horizon

We define virtualization as a set of techniques to run multiple operating systems on the same physical machine (physical node) sharing its resources. These technologies have a huge success because they improve safety, reliability and flexibility. Several studies in the field have been made by different teams, but the allocation of physical resources remains an open problem in the field of network virtualization. We identified this problem as a graph matching problem. We express and solve it like a Constraint Satisfaction Problem (CSP). Our CSP model includes Qos requirements and energy saving. To our knowledge, no previous work used CSP approach and combined Qos and Green aspects to allocate resources.

COPE and DCAR are basic network coding schemes which have been proposed for opportunistic network coding in wireless networks. The performances of these coding mechanisms have been studied by simulations or experiments. There is an interest in modeling the performances of these coding schemes mathematically. In fact, analytical approach can provide quicker performance analysis and comparison between these network coding schemes. In this paper, we propose an analytical model for the DCAR coding gain. The analytical results are validated by simulations in NS-2.

Adaptive redundancy control with network coding in multi-hop wireless networks
The 14th IEEE Wireless Communications and Networkings Conference
Vu Thuong Van, Boukhatem Nadia, Nguyen Thi-Mai-Trang and Pujolle Guy
Shanghai, April, 2013
Anglais - 6 p - Abstract
Recent research shows that random linear network coding is adapted into current network systems to provide transmission reliability. In lossy environments, like wireless networks, a redundancy control is also needed to mitigate losses. Some implementations suggest adding a fixed amount of redundant packets per batch. This solution poses the risk of wasting bandwidth by over-redundancy or unsuccessful decoding due to packet insufficiency, dramatically degrading the performance. In this paper, we present the Adaptive Redundancy Control for Network Coding (ARC) that adds redundant packets dynamically to mitigate losses. First, ARC is based on the use of MAC acknowledgements as a feedback on the state of link quality. Second, instead of determining the correct number of redundant packets, we decide to find the suitable time to send the redundant packets to cover losses. We design the multi-batch coding scheme that continuously streams new packets while interpreting the received MAC acknowledgements as the feedback on the state of link quality. The state of link quality will be rechecked before every transmission to deduct if it is appropriate for pumping the redundant packets or transmitting the new data. We implemented and compared ARC with 802.11 and FRC - Fixed Redundancy Control in NS-2. Results show that ARC outperforms 802.11 and FRC.

The future Internet is a term commonly related to research topics on new architecture for Internet. In fact, the Internet of tomorrow will rely on virtualization and cloud networking, which open the door for new security threats and attacks and address many problems related to identification, authentication, secure data transfer, and privacy in virtual networks and clouds. The purpose of our work is to define an architecture for strong authentication and identity management in virtual networks using EAP-TLS smart cards technology. The architecture is based on a Grid of EAP-TLS smart cards, as an authentication server, able to manage users' access to their virtual networks by authenticating either the user or the virtual network.

The exponential growth of the Internet and the diversity of services delivered to the end users, such as Cloud computing, have catalyzed researches on new generation networks. Hence, several proposals have been made to change the network applications and Internet media; in particular network virtualization is in the center of research interest. It is widely considered given its ability of dynamic programming, energy saving and low cost. This promising paradigm boosts different researches in literature. Openflow, AKARI and 4 ward projects are concrete examples. They follow common approaches of virtualization but with different characteristics. In this paper, we present an analysis and comparison between these projects. We mainly focus on Openflow solution to validate on demand virtual network architecture based on the Mininet simulator. This work is part of the On-Demand research project sponsored by European Regional Development Fund.

The future Internet is a term commonly related to research topics on new architecture for Internet. In fact, the Internet of tomorrow will rely on virtualization and cloud networking, which open the door for new security threats and attacks and address many problems related to identification, authentication, secure data transfer, and privacy in virtual networks and clouds. The purpose of our work is to define an architecture for strong authentication and identity management in virtual networks using EAP-TLS smart cards technology. The architecture is based on a Grid of EAP-TLS smart cards, as an authentication server, able to manage users' access to their virtual networks by authenticating either the user and the virtual network.

Flow-Based Power Control in Cognitive Radio Ad-Hoc Network
IEEE/ACM International Wireless Communications & Mobile Computing Conference (IWCMC) 2012

Cyprus, August, 2012
Anglais - 6 p - Abstract

Radio-Cognitive

In Cognitive Radio Networks (CRN), the appearance of more active primary users (PUs) might require blocking of one or more secondary user (SU) transmissions to maintain interference constraints at PU receivers and Quality of Service (QoS) constraints of SUs. In general, SU transmitters need to adjust their transmission powers to maintain these constraints at all times. In this paper, we are interested in maximizing the number of concurrent SU flows under new PU arrivals and performing power allocation for SU links belonging to maintained data flows to maximize the minimum flow capacity. In particular, we develop a flow maintenance and power control scheme to solve this problem, which is referred to as Flow-Based Power Control (FBPC). The proposed scheme comprises two phases where we attempt to find a best set of flows with maximum size in the first phase and maximize the minimum flow capacity through power control in the second phase. To reduce computation complexity required in the first phase, we develop a flow combination metric, which is used to find the best flow combination. Moreover, we formulate power allocation problem that maximizes the minimum flow capacity and show how to transform it into a geometric convex program. Numerical results are presented to show the efficiency of the proposed flow combination metric and the desirable performance of the proposed two-phase flow maintenance and power control scheme.

Decentralized Cooperative Spectrum Sensing for Cognitive Radio Ad-Hoc Network: Hidden Terminal Awareness Approach

Anglais - 1 p - Abstract

Radio-Cognitive

In Cognitive Radio Network, secondary users opportunistically use the licensed channels to transmit data. The secondary users first conduct the local sensing to determine the unoccupied channels and then choose the satisfied channel in the available channel set to transmit. However, the sensing results might not be accurate due to many problems: channel fading or shadowing, noise, hidden primary users or the aggregated interference caused by other secondary user transmissions. In this paper, we are interested in improving the spectrum sensing performance by reducing the missed-detection sensing caused by the hidden primary user problem. Particularly, we first proposed the channel state transition diagram capturing the hidden terminal possibility and then develop a collaborative scheme to exchange the sensing result between secondary users. Based on the summarized sensing results achieved from secondary user neighbors and proposed channel state diagram, each secondary will build its own channel table listing all available channels. Numerical results show that the proposed spectrum sensing scheme enhances the sensing results and the network performance.

OnDemand

Cloud computing is an emergent paradigm that allows customers to rent infrastructure, platforms and software as a service. With resource sharing and reuse through virtualization technology, cloud environments become even more cost effective and flexible. Nevertheless, networking within virtualized cloud still presents some challenges in performance and resource alloca- tion. In this paper, we propose DBA-VM, a Dynamic Bandwidth Allocator for Virtual Machines with regard to the established SLAs. The proposed scheme enforces the isolation between the virtual machines through the transmission bandwidth adjustment at the network I/O channel. The experimental performance evaluation shows that DBA-VM allows to the virtualized system to respect each virtual machine SLA while reducing the global physical resources (CPU and memory) consumption.

Distributed Opportunistic and Diffused Coding in Multi-hop Wireless Networks
EEE ICC workshop on Cooperative and Cognitive Mobile Networks
Vu Thuong Van, Nguyen Thi-Mai-Trang and Pujolle Guy
Ottawa, Canada, June, 2012
Anglais - 5 p - Abstract
In wireless mesh networks, network coding can be adapted and deployed for performance enhancement. Some early results such as COPE, BEND and DCAR show that the use of network coding can outperform the original 802.11 networks. However, these network coding architectures have two limitations: (i) the coding chances inevitably depend on the established route, (ii) traffic is strictly coded based on the two-hop coding pattern. In this paper, a novel and enhanced network coding architecture, Distributed Opportunistic Diffused Encoding (DODE), is proposed. DODE combines (i) the diffused gain from BEND and (ii) the generalized coding condition from DCAR to completely solve the limitations present in the three previous propositions. In addition, we propose a routing metric called Shortest Path with Enriched Neighborhood routing Metric (SPENM) which allows DODE to follow the most enriched coding chance path and also to enjoy the diffused gain. We implement DODE system in NS-2. The simulation results show that DODE outperforms 802.11, COPE, BEND and DCAR.

Gestion de la Mobilité

Multi-homing

Nowadays, wireless networks with heterogeneous technologies are largely deployed and, mobile terminals have multiple interfaces to access these networks. This raises many research issues such as the simultaneous access to heterogeneous networks and the mobility management. This paper proposes to manage the mobility of a terminal in this context. In particular, we want to guarantee that, while a terminal is moving from a given network to a different one, the quality of service of its applications will be maintained. For this purpose, we combine a multi-homing protocol (SHIM6) with an IMS architecture. The protocol SHIM6 ensures a seamless change of networks without any application disruption. The IMS architecture allows the establishment of multimedia session with quality of service. Our solution can manage the inter-domain mobility of a terminal in a reactive and proactive mode. For this purpose, we implement a SIP proxy inside the mobile terminal. The experimental evaluation shows the feasibility of the SHIM6-IMS integration and a considerable reduction of the handover delay.

Ingénierie du trafic Internet

We present a novel resilient routing policy for controlling the routing across peering links between Internet carriers. Our policy is aimed at offering more dependability and better performance to the routing decision with respect to the current practice (e.g., hot-potato routing). Our work relies on a non-cooperative game framework, called Peering Equilibrium MultiPath (PEMP), that has been recently proposed. PEMP allows two carrier providers to coordinate a multipath route selection for critical flows across peering links, while preserving their respective interests and independence. In this paper, we propose a resilient PEMP execution policy accounting for the occurrence of potential impairments (traffic matrix variations, intra-AS and peering link failures) that may occur in both peering networks. We mathematically define how to produce robust equilibrium sets and describe how to appropriately react to unexpected network impairments that might take place. The results from extensive simulations show that, under a realistic failure scenario, our policy adaptively prevents from peering link congestions and excessive route deviations after failures.

Virtualisation

In the few last years, the Internet has known an impressive success. This success has stimulated the development and the deployment of new technologies and advances applications. Nonetheless, due to its size and scope, this large network has become victim of its own success. Innovative approaches are required to overcome the shortfalls of current systems and to design Next Generation Internet. In this context, an ambitious vision of future Inernet would include network virtualization which presents a viable solution to deal with the current Internet impasse. It provides a promising way to deploy different network architectures and protocols over a shared physical infrastructure. However, in spite of its multiple advantages, network virtualization adds more complexity on network systems. A promising solution to address this huge complexity consists in developing systems which are capable of managing themselves, called autonomic computing systems or self-* systems. This paper proposes an agent-based autonomic framework which is able to self manage virtual resources. We provide a detailed description of the proposed autonomic architecture and we focus on a real test-bed implementation and testing of our framework. Experiment results show the ability of our system to self-configure its resources in order to maintain a required QoS level.

In this paper we propose CDEEC, a Connectivity Degree-based and Energy Efficient Clustering protocol, for wireless sensor networks in order to achieve further energy conservation while extending the network lifetime. The main idea behind our proposal is to consider, in addition to the information about the nodes' residual energy, the specific topology characteristics of the network, such as the connectivity degree, in the selection process of the cluster heads. To evaluate the performance of our proposal, we compare it to classical HEED-based (Hybrid, Energy-Efficient Distributed Clustering) networks. Simulation results show that significant energy conservation can be achieved.

Anglais - 16 p - Abstract

Ingénierie du trafic Internet

Inter-Autonomous System (AS) links represent nowadays the real bottleneck of the Internet. Internet carriers may coordinate to efficiently balance the load, but the current practice is often based on an uncoordinated selfish routing. Firstly, we assess this issue by characterizing BGP route deviations across top-tier interconnections we could detect using recent Internet routing history data. Then, in order to improve the current practice, we present a novel game-theoretical framework to efficiently coordinate the routing on inter-AS links while modeling the non-cooperative carrier behavior. It relies on a coordinated use of the Multi-Exit Discriminator (MED) attribute of BGP, hence it is nicknamed ClubMED (Coordinated MED). We define the routing policy that shall be implemented upon Nash equilibria and Pareto-efficient profiles. We emulated the interconnection between the Internet2 and the Geant2 networks, comparing our proposition to the current BGP practice. The results show that the route stability can significantly be reinforced, the global routing cost can be significantly reduced, and the inter-AS link congestion can be avoided.

Gestion de la Mobilité

The evolution of technologies, particularly the emergence of multi-interface terminals (3G, WLAN, WMAN, etc), totally changes the vision of services offered to users in the future. Multi-homing and multipath transmission support becomes more and more indispensable to satisfy user demands . Multipath TCP (MPTCP) is a modified version of Transmission Control Protocol (TCP) which allows using simultaneously multiple paths for data transmission. It aims to improve the throughput of TCP connection in a manner that a MPTCP connection over multiple paths should achieve at least a no worse throughput than a single TCP connection over the best constituent path. In a previous work, we have evaluated the load sharing of MPTCP without the coupled congestion control option. In this paper, the couple congestion control of MPTCP is enabled. The measurement results show that MPTCP with coupled congestion control provides a better performance. However, the heterogeneous networks environment (Ethernet, Wifi and 3G) still has a great impact on MPTCP throughput and reveals the need of an intelligent algorithm for interface selection in MPTCP.

Performance Improvements of Mobile SCTP during handover period

Luxembourg, June, 2011
Anglais - 5 p - Abstract

Gestion de la Mobilité

Handling mobility at the transport layer is an interesting approach to attain seamless handover in the context of heterogeneous access networks. To support terminal mobility, an extension of SCTP called SCTP-DAR (SCTP Dynamic Address Reconfiguration) (a.k.a. mobile SCTP) has been defined allowing SCTP endpoints to update IP address and inform the remote peer about primary address change. However, mobile SCTP suffers from performance degradation during handover. In this paper, we investigate two handover-related issues: reduction of data rate immediately after handover and packet reordering. The first issue is caused by the congestion control mechanism, which forces the ongoing traffic to enter the slow-start phase when moving into the new path after handover. The second issue is caused by the asymmetric characteristics of access networks such as the different bandwidths and delays in heterogeneous access networks. In order to solve these issues, we propose to use a combination of two mechanisms, congestion control parameter update and buffer retransmission.

Ingénierie du trafic Internet

The significant growth in the global Internet traffic and routing table size requires solutions to address Internet scalability and resiliency. A number of proposals have considered moving away from the flat legacy Internet routing to a two-level hierarchical routing, separating edge networks from transit carrier networks. In this paper, we study the extended inter-domain traffic engineering capabilities arising in a transit-edge separated Internet routing, focusing on those multi-homed edge networks (e.g., small ISPs, Cloud/content providers, large corporations) that aim at increasing their Internet resiliency experience. We model using game theory the interaction between distant independent edge networks exchanging large traffic volumes, with the goal of seeking efficient edge-to-edge load-balancing routing solutions. The proposed traffic engineering framework relies on a non-cooperative potential game, built upon path prepending- and path diversity- dependent costs, that indicates efficient equilibrium solution for the edge-to-edge load-balancing coordination problem. Simulations on real instances show that, in comparison with the alternative multipath BGP and normal LISP, we can achieve significantly higher resiliency and stability. In particular, our simulation for an illustrating case shows four-times more stable multipath routing solutions with a five-times larger path diversity

Virtualisation

Network virtualization is a promising technology that offers high levels of flexibility, isolation, extensibility and cost-effectiveness. In this paper, we focus on router virtualization. We evaluate the forwarding performance of virtual routers when the data plane runs in the guests. This scenario offers a high level of isolation and flexibility, however, it suffers from performance limitations due to the virtualization overhead. We show that the he I/O communication between the driver domain and the guests is the bottleneck. To overcome this limitation, we propose a new packets aggregation mechanism that transfers groups of packets between the driver domain and the guests. This enhancement makes the forwarding performance of one guest scale up to 1600 Kp/s. Furthermore, we propose a dimensioning tool in order to determine the maximum achievable throughput with regard to the container size.

Gestion de la Mobilité

Most of smart-phones are equipped with several network interfaces. This evolution highlights the benefits of multi-homing which offer user access to services not only anywhere, at any time and from any network but also simultaneously. Due to the lack of multi-homing support in existing protocols, several issues remain. The main issue is to manage several paths between two communicating nodes at a time in a mobile environment, and despite multiple paths, make sure end nodes correspond to the source and destination terminals. This paper proposes a SHIM6-based solution for the mobility management of mobile terminals in multi-homing context.

Routage dans les reseaux sans-fils

A Mobile Ad hoc NETwork (MANET) is a network without any pre-existing communication infrastructure. Wireless mobile nodes can freely and dynamically self-organize into arbitrary and temporary network topologies. There have been many challenges on the dynamic structure of MANET. One of those is to find the path from a source node to a destination node in the network. In this paper, we propose a formula of interference and a node-disjoint Interference-Aware Multi-Path OLSR routing protocol (IA-MPOLSR) which is based on the Optimized Link State routing protocol (OLSR) for MANET to increase the stability and reliability of the network. From our simulation results, we show that the IA-MPOLSR' packet delivery fraction is remarkably higher than the one of IA-OLSR, the original OLSR and OLSR-feedback. We also show that IA-MPOLSR' normalized routing load is lower than the corresponding results from IA-OLSR, the original OLSR and OLSR-feedback protocols

Gestion de la Mobilité

The main challenge in the development of future wireless communication systems is to pro- vide users with a wide range of services across different radio access technologies through a single mobile terminal, while maintaining the quality of service requirements. Thus, the need for seamless interworking between heterogeneous wireless communication systems consisting of multiple radio access technologies and overlapping networks emerges. In this article, we address the main issues that arise while implementing the interworking mecha- nisms between different radio access networks. An interworking mechanism based on IEEE 802.21 framework is proposed and described in detail. We combine concepts of autonomic networking in the design of the framework in order to use intelligence to provide flexibility, accessibility and transparency to the mobile users.

Secci Stefano and SANSÒ Brunilde
Vol. 46, No.1 , January, 2011
Anglais - Abstract

Maîtrise des réseaux

This paper deals with the design and dimensioning of a novel survivable optical network structure, called Petaweb, that can reach a total capacity of several Pb/s (1015 bit/s). The Petaweb has a composite-star architecture that allows two-hop connections between edge nodes through disconnected core nodes. Prior studies of the same authors have tackled the optimization of a Petaweb network architecture with regular and quasi-regular topologies. In this paper, reliability and survivability issues are addressed by introducing a dedicated path protection strategy into the design model. We present by extensive numerical results the reliability and survivability properties of the Petaweb core architecture with respect to single fiber link, core node, or switching plane failure and to switching site disconnection.

Stable and Accurate Time in Vehicular Networks
Ben-El-Kezadri Ryad and Pujolle Guy
December, 2010
Anglais - 6 p - Abstract
One fundamental limit for synchronizing a packet trace is that the two measurement systems that can be used to timestamp the packets, the operating system and the network interface, have mutually exclusive properties. The OS clock can be stabilized over the long run but the OS timestamps are not accurate; the PHY timestamps are accurate but they show a drift. To leverage the best features of both systems, we propose to stabilize the OS clock with a GPS and to remap the PHY timestamps over the OS/GPS time. This method is well suited for challenged scenarios like VANETs as no signaling is needed between nodes. We apply our approach to VANET monitoring and evaluate it on packet traces collected from our testbed. The results show that our solution reduces the mean synchronization error to 3 μs.

RFID

T2TIT

Radio Frequency Identification (RFID) is considered as an emerging technology for the Future Internet called the Internet of Things (IOT). It allows things and objects that embed RFID tags to be identified and to exchange information with each other. However, this new Internet is facing to some problems which are mainly related to the security of information exchange and the integration of RFID tags to the current Internet. The new version of the IETF Host Identity Protocol (HIP) proposed in the Thing to Thing in the Internet of Things project (T2TIT) overcomes the problem of security. Nevertheless, the integration of RFID tags into the IP world is still an open issue. Due to the lack of capacity and resources, these tags can not implement the entire IP stack. To address this issue, we propose in this paper, a new protocol HIP Address Protocol (HAT) that provides network services such as address translation system between the Tag RFID ID and IP addresses, encapsulation/decapsulation, fragmentation/reassembly and object mobility management services. We provide a detailed description of the proposed protocol. We also illustrate through significant scenarios how it operates.

Anglais - Abstract

Ingénierie du trafic Internet

In this paper, we study the inter-domain Autonomous System (AS)-level routing problem within an alliance of ASs. We first describe the framework of our work, based on the introduction of a service plane for automatic multi-domain service provisioning. We adopt an abstract representation of domain relationships by means of directional metrics which are applied to a triplet (ingress point, transit AS, egress point) where the ingress and egress points can be ASs or routers. Then, we focus on the point-to-point and multipoint AS-level routing problems that arise in such an architecture. We propose an original approach that reaches near optimal solutions with tractable computation times. A further contribution of this paper is that a heavy step in the proposed heuristic can be precomputed, independently of the service demands. Moreover, we describe how in this context AS-level path diversity can be considered, and present the related extension of our heuristic. By extensive tests on AS graphs derived from the Internet, we show that our heuristic is often equal or a few percent close to the optimal, and that, in the case of precomputation, its time consumption can be much lower than with other well-known algorithms.

Radio-Cognitive

The design of the future Internet is facing real challenges on network architecture. Attempts to resolve the issues related to naming/addressing, middle boxes, QoS-Security-Mobility interactions, cross-layer and inter-domain usually lead to endless debates. This is because the structure of the Internet has become too complex and has evolved with new functions added which are not always compatible with the existing functions. In order to analyze the architecture of the Internet in a strict manner, it is necessary to understand in depth the composition of functionalities within a protocol or between protocols. This paper presents a study on the composition of network functionalities and highlights future directions towards a theory for network architectures which includes the principles that network architectures should follow to ensure the normal operation of the member functions, detect all possible conflicts between them as well as figure out impossibilities.

Adapting virtualization concepts to satisfy network telecommunication challenges receives more and more attention. The virtual network environment is formed by the amount of bounded virtual resources provided by physical network equipments. Deploying virtual network infrastructure has recently caught more research interests due to its flexibility and manageability. However, virtual network deployment is not evident as it should be. Therefore, it is now necessary to provide virtual environment design to coexist virtual networks and their respective operators. In this article, we describe our virtual network environment architecture. We explain the proposed organization strategies to improve virtual network urbanization. The initial results and quantitative analysis of the architecture deployment are exposed. Keywords Virtualization - Network - Management - Urbanisation

Physical Rate and Contention Window Based Admission Control (PRCW) for 802.11 WLANs
IEEE Symposium on Computers and Communications
Didi Fedoua, Labiod H., Pujolle Guy and Feham M
Riccione, Italy, August, 2010
Anglais - 7 p - Abstract

Qualité de service dans les réseaux

Quality of service (QoS) is a key problem in wireless environments where bandwidth is scarce and channel conditions are time varying and sometimes implies highly packet losses. IEEE 802.11b/g/a wireless LAN (WLAN) are the most widely used WLAN standards today, and the IEEE 802.11e QoS enhancement standard exists and introduces QoS support for multimedia applications. This paper presents a class based admission control algorithm for 802.11e based wireless local area networks. The strengths of our admission control is dynamicity and flexibility of the algorithm, which adapts to the situation of the BSS, like global load, number of best effort AC, and position of QSTA by report of QAP, thing that have never been taken together, but each solutions have used a point of sight separately. Thus it achieves higher throughput than other admission control for 802.11 e. The idea which consists of changing parameters [AIFSN, CWmin and CWmax] of best effort flows, for decreasing collisions, is used, so we think that it is an efficient way to protect QoS flows from best effort flows, and to allow reducing then number of collisions. So we increase AIFSN [best effort flow], CWmin and CWmax only at 70% of load of network, to prevent starvations of best effort flows, and so we increase rate utilization of channel. We also use the current rate transmission of QSTAs, according to their positions, instead of the minimum rate transmission used by standard 802.11e, for calculate the load of network and derived the TXOPi necessary for all the stations, with i=1 to number of active stations. The 802.11e standard starves the low priority traffic in case of high load, and leads to higher collision rates, and did not make a good estimate of weight of queues, so there is an unbalance enters the flows with high priorities. A discussion is presented in detail using simulation-based evaluations, with an aim of comparing results of our admission control algorithm, with the 802.11e standard and the F- - HCF algorithm. Results reveal an improvement of the network load and a decrease of the number of collisions.

Ingénierie du trafic Internet

Although significant efforts have been devoted in the literature to measurements of the Internet topology, little attention has been given to the qualification of routing deviations and multipath dynamics at the Autonomous System (AS) routing level. We observed Internet AS-level routes toward thousands of destinations for several weeks between 2009 and 2010 to have a better understanding of these phenomena, nowadays. Using a modified form of traceroute at the state of the art called paris-traceroute, able to detect load-balancing, we sampled thousands of AS-level routes for several weeks. By an extensive analysis, we found that between 15% and 17% of the monitored destinations experiences AS-path deviations, and that load balancing at the AS-level (i.e., forms of BGP multipath) is not widespread at all, and, when frequently used, it is limited to a sort of AS confederation.

On the Minimization of Handover Decision Instability in Wireless Local Area Networks
International Journal of Computer Networks & Communications (IJCNC)
Abid Meriem, Ali Yahiya Tara and Pujolle Guy
May, 2010
Anglais - 13 p - Abstract

Horizontal Hand Over (HHO)

This paper addresses handover decision instability which impacts negatively on both user perception and network performances. To this aim, a new technique called The HandOver Decision STAbility Technique (HODSTAT) is proposed for horizontal handover in Wireless Local Area Networks (WLAN) based on IEEE 802.11standard. HODSTAT is based on a hysteresis margin analysis that, combined with a utilitybased function, evaluates the need for the handover and determines if the handover is needed or avoided. Indeed, if a Mobile Terminal (MT) only transiently hands over to a better network, the gain from using this new network may be diminished by the handover overhead and short usage duration. The approach that we adopt throughout this article aims at reducing the minimum handover occurrence that leads to the interruption of network connectivity (this is due to the nature of handover in WLAN which is a break before make which causes additional delay and packet loss). To this end, MT rather performs a handover only if the connectivity of the current network is threatened or if the performance of a neighboring network is really better comparing the current one with a hysteresis margin. This hysteresis should make a tradeoff between handover occurrence and the necessity to change the current network of attachment. Our extensive simulation results show that our proposed algorithm outperforms other decision stability approaches for handover decision algorithm.

Maîtrise des réseaux

Existing services require assurable end-to-end quality of service, security and reliability constraints. Therefore, the networks involved in the transport of the data must cooperate to satisfy those constraints. In a next generation Internet, each of those networks may be managed by different entities. Furthermore, their policies and service level agreements (SLAs) will differ, as well as the autonomic management systems controlling them. In this context, we in the Autonomic Internet (AutoI) consortium propose the Orchestration Plane (OP), which promotes the interaction among different Autonomic Management Systems (AMSs). The OP mediates the communication and negotiation among AMSs, ensuring that their SLAs and policies meet the requirements needed for the provisioning of the services. It also simplifies the federation of domains and the distribution of new services in virtualised network environments.

We consider the problem of cooperative distributed routing optimization in multi-domain/multi-provider networks. The main object of our investigation are ASON/G-MPLS transport networks, still the results of our investigations could be extended to any multi-domain network where particular domains have limited mutual visibility of intra-domain resources. This paper refines a distributed decomposition mechanism for reliable cooperative optimization of flow reservation levels introduced, by considering the fundamental issue of fair income distribution. The proposed idea of fair income distribution mechanism has been adopted from the theory of cooperative games (Shapley value). We show the benefits of adopting the proposed income distribution scheme by numerical simulations.

A Distributed Approach for Location Lookup in Vehicular Ad Hoc Networks
IEEE ICC 2009
Saleet Hanan, Langar Rami, Basir Otman and Boutaba Raouf
Dresden, Germany, June, 2009
Anglais - 6 p - Abstract

Gestion de la Mobilité

Efficient location management is one of the major challenges in Vehicular Ad Hoc Networks (VANETs). Due to the high mobility of vehicles and the increase in their number, the location information updating and querying messages will consume the limited bandwidth of VANETs. This involves the development of a scalable and locality-aware location service management protocol. In this paper, we propose a promising solution called the Modified Region-based Location Service Management Protocol (MRLSMP), which utilizes the existing infrastructure on the road as a location management service entity. To evaluate the efficiency of our proposal, we compare our scheme with existing solutions using both analytical and simulation approaches. Specifically, we develop analytical models to evaluate the total control overhead. Numerical and simulation results show that our protocol scales better than existing schemes, when increasing the size of VANETs which enhances the feasibility of such large scale ad hoc networks.

ADMA: Autonomous Decentralized Management Architecture for MANETs - A Simple Self-Configuring Case Study
IWCMC 2009, Autonomic Wireless Networking Workshop

Leipzig, Germany, June, 2009
Anglais - 6 p - Abstract
ADMA represents an Autonomous Decentralized Management Architecture designed to provide Mobile Ad Hoc Networks (MANETs) with autonomic principles. It allows the network to configure and reconfigure itself under environment changes without any human intervention. Our solution operates in a peer-to-peer manner and does not require any centralized entity to perform network management functions. Each mobile node implementing ADMA components is able to take the appropriate decision based on predefined high level policies and collected monitoring information. We present in this paper the basic components of an ADMA node. Then, we provide a simple self-configuring case study of our design considering Voice over IP (VoIP) as a test application. Simulation results show an improvement of the VoIP delay and loss rate while applying predefined policies.

XLEngine: a cross-layer autonomic architecture with network wide knowledge for QoS support in wireless networks
Berrayana Wafa and Pujolle Guy
Leipzig, Germany, June 21-24, 2009, June, 2009
Anglais - Abstract
The provision of Quality of Service (QoS) over wireless networks has recently been the subject of intensive research. There is a growing consensus among the research community that combining cross-layering and autonomic paradigms is, until now, the best alternative for better QoS support in such networks. The cross-layer concept is recommended to overcome the performance problems of the wireless channel, and the autonomic concept is imposed as the size and complexity of networks grow. Most proposed cross-layer architectures lack of autonomicity. Moreover, the majority of them considers purely local information in their optimizations and do not care about the effects of such egoistic behavior on other wireless nodes. This non-collaborative behavior limits the overall system performance. We combine cross-layering and autonomic concepts in the design of a new architecture called XLEngine (Cross-Layer Engine) having the ability to make optimizations based on local and network wide knowledge. We implemented XLEngine under the simulator J-Sim. We show, through simulations, that our XLEngine architecture significantly outperforms the layered architecture.

A Local View Management Protocol for Network-wide View construction in Wireless Networks
IEEE Global Information Infrastructure Symposium
Berrayana Wafa and Pujolle Guy
22-26 June 2009 Hammamet, Tunisia, June, 2009
Anglais - 8 p - Abstract
Combining cross-layering and autonomic paradigms is considered, until now, the best alternative for better Quality of Service (QoS) support in wireless networks. We adopt this combination in the design of a new architecture called Cross- Layer Engine (XLEngine) having the ability to make optimizations based on local and network wide knowledge. The unique mode to acquire this network knowledge is that every node notifies other nodes about its local metrics (called local view). To achieve this goal, we propose a new protocol called the Local View Management Protocol (LVMP). LVMP implements a selective rebroadcast technique to reduce the number of nodes participating in the local view dissemination process while assuring that this local view attains all nodes. We give a performance evaluation of LVMP and we study the impact of the overhead on the overall XLEngine performance.

This paper presents a testbed implementation of an inter-carrier GMPLS (generalized multi protocol label switching) service architecture recently proposed. This architecture couples the path computation element (PCE)-based control plane with a service plane managing discovery, composition and activation functions of inter-carrier service elements. The testbed implements the required PCE communication protocol (PCEP) and resource reservation protocol with traffic engineering (RSVP-TE) extensions, together with service request filtering operations performed with a policy based architecture.

Routage dans les reseaux sans-fils

One of the major concerns in wireless mesh networks (WMNs) is the radio resource utilization efficiency, which can be enhanced by managing efficiently the mobility of users as well as the interference effect among neighboring links. To achieve this, we propose in this paper the use of clustering and a new interference-aware routing metric, called INX Specifically, we first propose two mobility-aware clustering algorithms that take into consideration the mobility properties of users in order to improve the WMN performance. Then, we propose the use of INX in the clustering process in order to maximize the total network throughput. We prove through simulations that both clustering schemes can achieve significant gains in terms of radio resource utilization and load balancing, especially when using the INX metric. Hence, and as a main contribution, we show that by taking into account the interference effect between links, we can improve the performance of our clustering algorithms and increase the gain initially observed with the conventional hop-count metric.

Anglais - Abstract
We consider a cross-layer scheme for the downlink multiuser Orthogonal Frequency Division Multiple Access (OFDMA) for mobile WiMAX (Worldwide Interoperability for Microwave Access) based on IEEE802.16e standard. We propose an intelligent Medium Access Control (MAC) that adapts with the physical layer (PHY) in response to the different QoS requirements of the diverse service flows in the system. This adaptation is represented by a joint packet scheduling and slot allocation scheme interaction in both MAC and PHY layers. Based on this interaction, a fair and efficient QoS guaranteed resource allocation for a mixture of real-time and non real-time service flows is achieved. We provide extensive simulation results showing the performance aspects of the proposed cross-layer scheme.

One of the major challenges for Vehicular Ad Hoc Networks (VANETs) is related to efficient location management issue. In this paper, we propose a new Region-based Location Service Management Protocol (RLSMP) that uses mobility patterns as means to synthesize vehicle movement and thus can be used in VANETs applications. One of the key distinguishing features of our solution from existing literature is its scalability since it uses message aggregation in both updating and querying, and promises locality awareness as well as minimum signaling overhead. To evaluate the efficiency of our proposal, we compare our scheme with existing solutions using both analytical and simulation approaches. To achieve this, we develop analytical models to evaluate the location updates cost. Numerical and simulation results show that our protocol scales better than existing schemes, when increasing the size of VANET which enhances the feasibility of such large scale ad hoc networks.

A cross-layer autonomic architecture for QoS support in wireless networks

Dubei-UAE, November, 2008
Anglais - 6 p - Abstract
Cross-layering is a novel paradigm in wireless local area networks (WLAN) proposed to improve the support of QoS (Quality of Service) traffic. Many cross-layer solutions have already been developed. They diverge in the way the crosslayer concept is implemented and the type of performance gain they recommend. In parallel to cross-layering, a new network paradigm is growing: the autonomic paradigm appearing as the size and complexity of networks grow. There is a growing consensus among the research community that combining cross-layering and autonomic paradigms is, until now, the best alternative for better QoS support in WLANs. We combine cross-layering and autonomic concepts in the design of a new architecture called XLEngine (Cross-Layer Engine) having the ability to make optimizations based on local and network wide knowledge. XLEngine is implemented and simulated under the JSim simulator for different wireless scenarios. Simulation results show that XLEngine outperforms the classic layered architectur

Anglais - 5 p - Abstract

In the new area of heterogeneous environments, roaming users, using multi-interface mobile terminals, need to access to services anytime and anywhere. For that, a seamless vertical handover has to be considered. In our paper, we propose a 3G/UMTS-WLAN loosely-coupled interworking architecture with Mobile IP as a service continuity solution. We focus on a mobile-controlled vertical handover management scheme. Our solution chooses the best access network according to user preferences and it maintains the ongoing session. It has several advantages to be simple and to generate minor changes at the network side. Moreover, MIP-based handover execution procedure is prepared thanks to a handover decision taken at the mobile side. The scheme proposes an interesting answer to intersystem and inter-domain mobility management issues. Finally, a simulation model is developed to validate the feasibility of the proposed 3G/UMTS-WLAN architecture.

In this letter, we propose a cooperation-aware routing scheme based on long-term statistics of cooperative links. The proposed scheme fully exploits cooperation on fading scenarios and proves to be more efficient than greedy cooperation-aware routing based on instantaneous link conditions. Moreover, the performance improvement is even higher when cooperative and non-cooperative nodes coexist.d

Channel Aware Scheduling for multiple Service Flows in OFDMA Based Mobile WiMAX Systems
VTC2008-Fall

Alberta, Canada, September, 2008
Anglais - 5 p - Abstract
We consider a channel aware scheduling for the downlink multi-service flows in Orthogonal Frequency Division Multiple Access (OFDMA) based mobile WiMAX (Worldwide Interoperability for Microwave Access)system. We propose an intelligent Medium Access Control (MAC) that adapts with the physical layer in response to the different QoS requirements of the diverse service flows in the system. This adaptation is represented by a joint packet scheduling and slot allocation scheme interaction in both MAC and PHY layers. Based on this interaction, a fair and efficient QoS guaranteed resource allocation for a mixed real-time and non real-time service flows is achieved. We provide extensive simulation results showing the performance aspects of the proposed cross-layer scheme.

Performance Comparison of Polling Mechanisms in IEEE 802.16 Networks

Cardiff, Wales, UK, September, 2008
Anglais - 6 p - Abstract
IEEE 802.16 standard suite defines two main polling mode: unicast polling and contention-base polling including multicast and broadcast polling. Unicast polling completely overcomes the request collision and is suitable for real-time application. Contention-based polling suffers from collisions and be suitable for non-real-time applications. While the standard defined uplink scheduling services for implementing effectively the polling mechanisms, it does not define how exactly adaptation algorithm should be developed. In this paper we evaluate the performance of different polling mechanisms defined in IEEE 802.16 by simulation. We also propose a new optimal unicast and contention-based mixed polling mechanism and showed that this optimal mixed polling mechanism could always achieve better performance than any polling mechanisms defined in IEEE 802.16.

Anglais - 15 p - Abstract
Networks are becoming service-aware implying that all relevant business goals pertaining to a service are fulfilled, and also the network resources are used optimally. Future Internet Networks (FIN) have time varying topology (e.g. such networks are envisaged in Autonomic Internet [1], FIND program [2], GENI program [3], FIRE program [4], Ambient Networks [5], Ad-hoc networks [6]) and service availability and service context change as nodes join and leave the networks. In this paper we propose and evaluate a new self-organising service management system that manages such changes known as the Overlay Management Backbones (OMBs). The OMB is a self-organising solution to the problem space in which each OMB node is dynamically assigned a different service context task. The selection of OMB nodes is conducted automatically, without the need of relatively heavyweighted dynamic negotiations. Our solution relies on the scalability and dynamicity advantages of Distributed Hash Tables (DHTs). This system is needed to select continuously, automatically, and dynamically a set of network nodes, to become responsible for collecting the availability information of service context in the changing network. This solution advances the state of the art avoiding dynamic negotiations between all network nodes reducing management complexity and cost for bandwidth-limited environments.

An Intelligent Handover Management System for Future Generation Wireless Networks
EURASIP Journal on Wireless Communications and Networking
Kassar Meriem, Kervella Brigitte and Pujolle Guy
August, 2008
Anglais - 12 p - Abstract

Future generation wireless networks should provide to mobile users the best connectivity to services anywhere at anytime. The most challenging problem is the seamless intersystem/vertical mobility across heterogeneous wireless networks. In order to answer it, a vertical handover management system is needed. In our paper, we propose an intelligent solution answering user requirements and ensuring service continuity. We focus on a vertical handover decision strategy based on the context-awareness concept. The given strategy chooses the appropriate time and the most suitable access network among those available to perform a handover. It uses advanced decision algorithms (for more efficiency and intelligence) and it is governed by handover policies as decision rules (for more flexibility and optimization). To maintain a seamless service continuity, handover execution is based on mobile IP functionalities. We study our decision system in a case of a 3G/UMTS-WLAN scenario and we discuss all the handover decision issues in our solution.

Gestion de la Mobilité

Efficient mobility management is one of the major challenges for next-generation mobile systems. Indeed, a mobile node (MN) within an access network may cause excessive signaling traffic and service disruption due to frequent handoffs. The two latter effects need to be minimized to support quality-of-service (QoS) requirements of emerging multimedia applications. In this perspective, we propose in this paper a new mobility management scheme designed to track host mobility efficiently so as to minimize both handoff latency and signaling cost. Building on and enhancing Mobile IP and taking advantage of MPLS traffic engineering capability, three mechanisms (FH-, FC- and MFC-Micro Mobile MPLS) are introduced. In order to assess the efficiency of our proposals, all protocols are compared. To achieve this, we develop analytical models to evaluate the signaling cost and link usage for both two-dimensional and one-dimensional mobility models. Additional mathematical models are also provided to derive handoff latency and packet loss rate. Numerical and simulation results show that the proposed mechanisms can significantly reduce the registration updates cost and provide low handoff latency and packet loss rate under various scenarios.

Distributed Policy Management Protocol for Self-Configuring Mobile Ad Hoc Networks
Advances in Ad Hoc Networking, IFIP Proceedings of the 7th Mediterranean Ad Hoc Networking Workshop
Ayari Mouna and Pujolle Guy
Palma de Mallorca, Spain, August, 2008
Anglais - 73 p - Abstract
Mobile ad hoc networks (MANETs) are fundamentally different from wired networks. They are autonomously formed with a collection of mobile nodes without any preexisting infrastructure or administrative support. In the last few years, Policy-Based Network Management (PBNM) has gained a considerable interest in order to reach adaptive and automated management goals in MANETs. Previous work in this ﬁeld either cluster-based or hierarchical architectures are highly dependent of the network topology. A distributed approach with a high degree of autonomy and self-management is still lacking. In this paper, we give an overview of existing policy-based management solutions and we focus on some of their limitations. We outline the need of incorporating self-conﬁguration property in the design of MANETs. Then, we present a new protocol for distributing policies and high level goals over all nodes in the network. Simulation-based performance evaluation results are described and analyzed.

This paper analyzes a trust model for mobile ad hoc networks. We provide nodes with a mechanism to build a trust relationship with its neighbors. The proposed model considers the recommendation of trustworthy neighbors and the experience of the node itself. The interactions are limited to direct neighbors in order to scale on mobile networks. The results show the efficiency and the trade-off of our model in the presence of mobility. We also analyze the advantages of considering the relationship maturity, i.e. for how long nodes know each other, to evaluate the trust level. The maturity parameter can decrease the trust level error up to 50%.

Slander attacks represent significant danger to distributed reputation systems. Malicious nodes can ally to lie about their neighbors and cause serious damage to the trust evaluation system. This paper presents and analyzes a trust model robust against slander attacks in ad hoc networks. We provide nodes with a mechanism to build a trust relationship with its neighbors. The proposed model considers the recommendation of trustworthy neighbors and the experience of the node itself. The interactions are limited to direct neighbors in order to scale on mobile networks. The results show the impact of slander attacks to our trust model. We analyze how the main parameters affects the trust evaluation process and how they can be tunned to improve the efficiency of the trust system.

Performance Optimization for Delay-tolerant and Contention-based Application in IEEE 802.16 Networks

USA, July, 2008
Anglais - 14 p - Abstract
IEEE 802.16 standard suite defines the air interface specifications for fixed and mobile broadband access in wireless metropolitan area networks. Although the IEEE 802.16 MAC has been well-defined by various bandwidth allocation and scheduling mechanisms to support QoS for different applications, efficient bandwidth allocation still remain as an open issue. In this paper, we analyse and develop a mathematical model to evaluate the performance of the contention-based and delay-tolerant applications in IEEE 802.16 networks. We focus our attentions on allocating the uplink bandwidth efficiently, the basic goal is to optimize the performance with an optimal bandwidth allocation mechanism. The results of our analysis lay out clearly that a maximum uplink throughput and a minimum number of pending bandwidth request transmission can always be acquired by optimizing the contention period size in a frame. This optimal size is also influenced by the number of terminals in the network, which is also analyzed in the later part of the paper. Our results can be used for providing probabilistic throughput guarantee and determining the optimal contention period.

Towards Autonomous Mobile Ad Hoc Networks: A Distributed Policy-Based Management Approach
The Fourth International Conference on Wireless and Mobile Communications
Ayari Mouna and Pujolle Guy
Athens - Greece, July, 2008
Anglais - 6 p - Abstract
Mobile ad hoc networks (MANETs) are spontaneously formed with a set of wireless nodes without any existing infrastructure or administrative support. The intrinsic characteristics of these networks such as the dynamic topology and the scarcity of resources mainly bandwidth and nodes battery life make network management process a challenging task. In this paper, we present the design and a performance evaluation of a distributed policy management system that aims to enable self-QoS-management of MANETs. The key idea is to extend policy decision point (PDP) functionalities to every mobile ad hoc node in order to support self-conﬁguration and self-adaptation capabilities. We propose the management of the MANET in a fully distributed manner using a new protocol named DPMP for Distributed Policy Management Protocol. First, we present our decentralized framework. Then, we evaluate the proposed policy distribution mechanism through simulations. Results show that the protocol incurs low latency and message overhead for policies distribution while varying node mobility, network size and density.

In this article, we contribute on the service-driven management of quality of service and user access in wireless corporate networks. We propose a Service-Level Agreement(SLA) oriented nomadism management architecture with a top-down vision starting by the specification of company objectives and going down to device-level configurations. We define an algorithm for the automatic translation of application-level quality assurance parameters into network-level configuration parameters. A prototype implementation of our solution to the SLA-driven enterprise nomadism management is presented along with preliminary results on the self-adaptive capabilities of our QoS mapping algorithm.

A Novel Connection Setup Management Approach for Optical WDM Networks
IEEE Communication Letters
Fawaz Wissam, Chen Ken and Abou-Rjeily Chadi
January, 2008
Anglais - 3 p - Abstract
Wavelength Division Multiplexing (WDM) has significantly increased the transmission capacity of todayNULLs optical networks. An increase in the available bandwidth is promoting at the same time the introduction of new services, each having different Quality of Service (QoS) requirements. In this regard, QoS parameters applicable to connection setup, namely connection blocking probability and connection setup time, are expected to greatly influence the procedure of lightpath setup. In view of this, we propose to consider the connection setup time requirement as a (timely increasing) priority indicator during optical connection provisioning. In other words, we envisage in this letter the assignment of the highest setup priority to those optical connection requests having the shortest setup time requirements. To achieve this purpose, we adapt the well known Earliest Deadline First (EDF) scheduling discipline to the particular case of optical connection setup management. In order to gauge the impact of our proposal on the QoS perceived by optical clients, we introduce in this letter a computaional method. This latter is used for the assessment of the percentage of optical connections that are successfully established under the proposed setup management approach.

An Overview of Vertical Handover Decision Strategies in Heterogeneous Wireless Networks

January, 2008
Anglais - 14 p - Abstract

Gestion de la Mobilité

In the next generation of wireless networks, mobile users can move between heterogeneous networks, using terminals with multiple access interfaces and non-real-time or real-time services. The most important issue in such environment is the Always Best Connected (ABC) concept allowing the best connectivity to applications anywhere at anytime. To answer ABC requirement, various vertical handover decision strategies have been proposed in the literature recently, using advanced tools and proven concepts. In this paper, we give an overview of the most interesting and recent strategies. We classify it into five categories for which we present their main characteristics. We also compare each one with the others in order to introduce our vertical handover decision approach.

YAVISTA: A Graphical Tool for Comparing 802.11 Simulators
Ben-El-Kezadri Ryad
January, 2008
Anglais - 11 p - Abstract - Fichier : afficher
The difficulty to compare network simulators is a major obstacle to the broader adoption of these tools. This problem particularly affects 802.11 simulators because the 802.11 protocol is complex and simulators contain several simplifications that are difficult to evaluate. In this paper, we present a generic visualization system able to interface with the 802.11 protocol implemented in NS-2 and Glomosim. Our tool allows to emphasize the common behaviours and divergences observed between the simulators and the IEEE 802.11 standard. Our contribution includes the definition of a new method to compare simulators and the publication of the most complete list to date of modeling differences relative to NS-2 and Glomosim lower layers.

A Flexible Channel Access Model for Wireless Network Interface Cards
Ben-El-Kezadri Ryad
Bangalore, January, 2008
Anglais - 7 p - Abstract
Wireless network interface cards (WNIC) are currently moving from hardwired devices to autonomic software. This paper proposes a new rationale for the design of WNIC that i) takes into account the need to integrate an ever increasing number of network features, ii) supports the traceability of requirements in system development and iii) allows flexibility at the software architecture level. Our solution relies on the FODA (feature oriented domain analysis) and FORM (feature oriented reuse method) engineering methods to bridge the gap between the systemspsila specification and implementation. As an example, we show how a model of the 802.11 standard based on this method can reproduce the features of a particular channel access protocol or be extended to the 802.11g standard.

XAV : A Fast and Flexible Tracing Framework for Network Simulation
Ben-El-Kezadri Ryad and Pujolle Guy
Vancouver (Canada), January, 2008
Anglais - 7 p - Abstract
With current network simulators, simulation results are obtained from flat trace files via sequential data access. To speed up simulation output analysis, we propose to store the simulation traces into data warehouse. Our proposed framework relies on a three-layer architecture, with the intermediary database layer serving the trace file post processing services. The trace files are accessed through SQL-like queries which greatly enhances the flexibility of the post processing tools. Furthermore, the database paradigm allows to separate the packets data from the nodes send and receive operations and thus to remove redundant information between simulation events. The global system relies on a new trace file format based on the popular XML language. XML pointers are used to create relationships between data so that post processing tools can navigate into simulation outputs. The tests are carried out under the MonetDB database. The obtained results show considerable response time improvement compared to traditional sequential access mode.

A Pilot-based Autonomic Architecture for the Control of Future Networks
International Conference on Telecommunications and Multimedia (TEMU)
Pujolle Guy, Abid Meriem and Movahedi Zeinab
Crete - Greece, January, 2008
Anglais - 14 p - Abstract
TodayNULLs networks are made of a large number of Network Elements (NEs) such as routers, firewalls, gateways, hosts, etc., each performing a set of elementary functions related to routing, security management, resource reservation, QoS management, etc. More sophisticated functions such as configuration of NEs, optimization of routing tables, troubleshooting, etc., are mainly managed in a centralized fashion often involving human intervention. However, networks are more and more faced with rapidly changing situations and increasingly complex configurations which are harder and harder to be adequately managed in a centralized manner, because of timing issues (collecting and processing information takes time) and complexity issues (dealing with networks centrally/globally is increasingly complex). In this paper we propose a Pilot-based Architecture (P2A) for future network control and management. This architecture is based on Distributed Intelligent Agents. This solution permits to perform a number of control and management functions in a decentralized way, dealing locally with simpler situations in a more responsive way. The P2A is made of Distributed Intelligent Agents, each capable of sensing and observing events and changes occurring locally. Agents communicate among neighbours to improve their knowledge of the situation in their neighbourhood and to make consolidated/coordinated decisions within an area of the network.

Priority-enabled Optical Shared Protection: an Online Efficiency Evaluation Study
Computer Communications
Chen Ken and Pujolle Guy
Elsevier, December, 2007
Anglais - Abstract
The availability of an optical connection is considered to be a critical service differentiator in WDM optical networks. In this regard, the design of a protection scheme that is able to improve the availability of high priority connections while making efficient use of optical resources is a major concern for optical network perators. In a previous work, we proposed the so-called priority-aware shared protection as a potential survivability scheme for next generation WDM networks to deal with the previously exhibited concern. This paper develops an online study whose main purpose is to assess the efficiency of the aforementioned protection scheme. Through this study, we show that the priority-aware shared protection strategy is able to achieve both the best efficiency in terms of resource usage and in terms of availability satisfaction rate compared to existing protection solutions.

Anglais - 6 p - Abstract
In the next generation of wireless networks, mobile users should move across various access technologies, using multi-interface terminals and different types of services. The most important issue in such heterogeneous environment is the Always Best Connected (ABC) concept. It allows the best connectivity to services anywhere at anytime. For that, a seamless inter-system handover solution is needed. In our paper, we propose an intelligent solution, based on the context-awareness concept, ensuring service continuity and answering user requirements. We focus on the vertical handover decision issue. It performs whether and over which access network to hand over among those available. It uses advanced decision algorithms (for more efficiency and intelligence) and it is governed by handover policies as decision rules (for more flexibility and optimization).

WiMax bandwidth provisioning service to residential customers
IFIP/IEEE International Conference on Mobile and Wireless Communications Networks
khemiri Sondes and Pujolle Guy
Cork, Irlande, September, 2007
Anglais - 5 p - Abstract
In this paper, we propose a mathematical model with the aim to give guidelines for the dimensioning of WiMax bandwidth provisioning service to residential customers. Our proposal relies on the modeling of a CAC policy associated to a priority-based bandwidth sharing strategy. Both mechanisms aim to satisfy Quality of Service constraints while maximizing the gain of the system. But unlike in [1], we do not necessarily seek here for an optimal CAC policy. We rather consider a coordinate convex CAC policy, whose mathematical modeling leads to a tractable analytical resolution. We chose the Guaranteed Minima (GM) policy, which consists in reserving a specified amount of bandwidth for each traffic class. The remaining bandwidth is shared between all traffic classes.

Cross-layering is an innovative concept in ad hoc networks for efficient multimedia transmissions in terms of providing better QoS (Quality of Service) support over a capacity-limited wireless channel. Many cross-layer proposals are already developed. They diverge in the way the sharing cross-layer concept is implemented and the type of performance gain they recommend. We propose a new cross-layer architecture, called XLEngine, for protocol QoS extensions in ad hoc networks. XLEngine is characterized by its generic nature and by its ability to support networkwide optimizations. This means that every node can have an overview of the network-wide state. To achieve this networkwide view, we propose the Local View Management Scheme (LVMS).

This paper introduces a new model dedicated to the Internet of Thing that interacts with active RFIDs. Instead of targeting IP stacks implementation in tags, we plan to support the Host Identity Protocol, which dissociates IP address and host location and that has been recently defined by the Internet Engineering Task Force (IETF). We propose an architecture, in which a PORTAL entity realizes the bridge between classical IP world (compatible with the EPCglobal infrastructure) and HIP domains, dealing with a constellation of readers and tags.

Optimal Call Admission Control for an IEEE 802.16 Wireless Metropolitan
International Conference on Network Control and Optimization
khemiri Sondes, Boussetta Khaled and Pujolle Guy
Avignon, France, June, 2007
Anglais - 10 p - Abstract
This paper focus on optimal Call Admission Control (CAC) policy for an IEEE 802.16 Wireless MAN. This policy has two objectives: (i) statistically guarantee the QoS of UGS, rtPS and nrtPS connections, (ii) maximize the average revenue of the wireless link. To find such optimal policy, we model our CAC agent as a Constrained Semi-Markov Decision Processes (CSMDP). To the best of our knowledge, the only algorithm able to compute the optimal control policy of a CSMDP is based on the Linear Programming (L.P.) approach. Unfortunately, a realistic CAC problem with a large states space is intractable with the L.P. algorithm. Our work presents two contributions. First, the proposition of an optimal CAC for Triple-Play services support over a 802.16 WMAN. Second, the presentation of an alternative iterative algorithm that can be used to overcome the difficulties faced by the L.P. approach.

Business-driven optimization of policy-based management solutions
10th IFIP/IEEE International Symposium on Integrated Network Management (IM 2007)

Munich, Germany, May, 2007
Anglais - 10 p - Abstract - Fichier : afficher
We consider whether the off-line compilation of a set of Service Level Agreements (SLAs) into low-level management policies can lead to the runtime maximization of the overall business profit for a service provider. Using a simple web application hosting SLA template for a utility service provider, we derive low-level QoS management policies and validate their consistency. We show how the default first come first served (FCFS) mechanism for the runtime scheduling of triggered policies fails to deliver an all times maximum business profit for the service provider. To achieve a better business profit, first a penalty/reward model that is derived from the SLA Service Level Objectives (SLOs) is used to assign runtime utility tags to triggered policies. Then three policy scheduling algorithms, which are based on the prediction of the future state of the running SLAs, are used to drive the runtime actions of the Policy Decision Point (PDP). The prediction function per see involved the unsolved problem of predicting in realtime the evolution of the transient state of a variant of an M/M/Ct/Ct queue. A simple approximative solution to the latter problem is provided. Finally, using the PS policy simulator tool, comparative simulation results for the business profit generated by each of the proposed policy scheduling algorithms are presented. PS is a novel tool which we have developed to respond to the increasing need of benchmarking SLA and policy-based management solutions.

Anglais - 7 p - Abstract - Fichier : afficher
This paper presents PS, a Policy Simulator tool intended to serve in the validation and performance evaluation of policy-based management solutions. PS is a discrete processbased simulation environment which allows the specification of all major components required for a policy-based management solution. These include the ability to specify management policies, events, metrics, probes, service-level objectives, servicelevel agreements (SLAs), as well as business-level objectives. We describe the main components of PS and show how it has been used to evaluate the performance of a policy-based management solution for a web application hosting SLA.

Using OLSR Multipoint Relays (MPRs) to estimate node positions in a Wireless Mesh Network
European Wireless 2007 (EW2007)
Mühlethaler Paul
Paris, April, 2007
Anglais - Abstract
In this paper we address the problem of node localization in wireless heterogeneous networks focussing particularly on anchor selection methods to estimate position. The Optimized Link State Routing protocol (OLSR) [1] uses special nodes called Multipoint Relay (MPR) nodes to broadcast control messages within the network. We propose a novel approach based on using these Multipoint Relay (MPR) nodes as anchor nodes to estimate nodes positions. We evaluate its performance by simulation and compare it to other selection techniques such as convex hull selection and greedy selection.

Graphic Visualization of the 802.11 DCF Protocol Under the NS-2 Simulator

Norfolk Virginie Etats-Unis, March, 2007
Anglais - 10 p - Abstract - Fichier : afficher
The IEEE 802.11 standard uses the Distributed Coordination Function (DCF) protocol to share the medium among multiple stations. DCF is implanted in all the mobile ad-hoc networks (MANET) simulators but its validation poses a true problem considering both the diversity of the models and their simplicity. The validation systems being hard to implement, the visualization tools represent, by comparison, auxiliary applications much more simple to develop. Behind their apparent simplicity, the graphic traces are extremely powerful teaching aids able to bring images of the DCF dysfunctions observed during the simulation execution. For this purpose, the simulation events are logged in trace files and then displayed in the form of timeline. The main contribution of this work is the definition of a tool allowing visualization of the network simulators activity at the data link layer. To show the potential of the approach, screenshots showing the dysfunctions observed in the NS-2 simulator are presented and analyzed.

This paper introduces a new model dedicated to the Internet of Thing that interacts with active RFIDs. Instead of targeting IP stacks implementation in tags, we plan to support the Host Identity Protocol, which dissociates IP address and host location and that has been recently defined by the Internet Engineering Task Force (IETF). We propose an architecture, in which a PORTAL entity realizes the bridge between classical IP world (compatible with the EPCglobal infrastructure) and HIP domains, dealing with a constellation of readers and tags.

In this work, we focus on the service-driven management of quality of service and user access in wireless corporate networks. We adopt a novel approach in dealing with the problem. We aim at automatic equipment configuration based on high level company objectives and strategies for nomadism. For that, we propose a service-oriented management system with a top-down vision, which starts at the specification of company objectives and strategies and down to until reaching instance configuration. To illustrate our proposal we present the implementation steps of a nomadism in the enterprise use case.

Proposition of a cross-layer architecture model for the support of QoS in ad-hoc networks
2nd CoNEXT Conference, ADETTI/ISCTE 4-7 December
Berrayana Wafa , Habib Youssef, Lohier Stéphane and Pujolle Guy
Lisboa, Portugal, December, 2006
Anglais - Abstract
Due to the lack of built-in quality of service support, IEEE 802.11 ad-hoc networks presents serious defies in meeting the demands of multimedia applications. To overcome such challenges, research in providing QoS guarantee in ad-hoc networks has been widely studied in latest years, and several QoS bapproaches have been proposed. Actually, cross-layer approaches have fascinated the attentions of researchers. They have interested at particular features of network performance by developing a multitude of cross-layer optimizations and adaptations implemented into several cross-layer architectures. We think that it is time that these various personal efforts be put into perspective; and that it is time to have a cross-layer architecture model which can serve as blueprint for development of cross-layer systems. In this paper, we take a step in that direction.

SSTF: A `Shortest Setup Time FirstNULL Optical Connections Setup Management Approach with Quantifiable Success Rate
IEEE Globecom 2006
Chen Ken
San Francisco, California, USA, November, 2006
Anglais - 5 p - Abstract
The worldwide network domain tendency to evolve towards dynamic Quality of Service (QoS) enabled optical networks is imminent. In such an evolution, imporving connection setup conditions is considered to be one of the major requirements. This paper proposes a novel connection setup management approach. The rationale behind this proposal lies in considering the optical connection setup time requirement as a (timely increasing) priority indicator during the setup/provisioning process. From this viewpoint, we adapt the well known Earliest Deadline First (EDF) scheduling discipline to the particular case of optical connection setup management, which consists in giving highest priority to the connection request having the shortest setup time requirement. Another originality of this paper stems from the proposal of a computaional method for the assessment of optical connection setup success probability under the proposed management approach. The latter parameter, that is the connection setup success rate, is an important indicator for both optical operators and clients.

In this paper we present a comparison among three different monitoring functions to be used in a dynamic bandwidth renegotiation scheme. These functions aim at detecting the amount of unused resources in the network, which can be allocated to low priority data flows. These applications are not delay-sensitive and can be admitted by the call admission control with a bandwidth smaller than the nominal one. Simulation results comparing the performance of the three monitoring functions are presented, as well as an overhead analysis. Finally, we discuss the performance/complexity trade-off considering the three functions and determine the most viable one.

GXLA a Language for the Specification of Service Level Agreements
Lecture Notes in Computer Science, Springer Berlin / Heidelberg
Tebbani Badis
Paris, September, 2006
Anglais - 14 p - Abstract
In this work we propose GXLA, a language for the specifica- tion of Service Level Agreements (SLA). GXLA represents the implemen- tation of the Generalized Service Level Agreement (GSLA) information model we proposed in a previous work. It supports multi-party service relationships through a role-based mechanism. It is intended to catch up the complex nature of service interactivity in the broader range of SLA modeling of all sorts of IT business relationships. GXLA is defined as an XML schema which provides a common ground between the entities in order to automate the configuration. GXLA can be used by service providers, service customers, and third parties in order to configure their respective IT systems. Each party can use its own independent SLA inter- pretation and deployment technique to enforce the role it has to play in the contract. An illustrative VoIP service negotiation shows how GXLA is used for automating the process of SLA negotiation and deployment. Keywords: Self Configuration; Service Level Agreement; Policy Based Management; SLA Specification, Policy Specification.

Anglais - Abstract
Third generation (3G) mobile cellular systems are available for higher capacity than previous generations deployed in many countries around the world. Design and developments beyond 3G are aiming not only for higher capacity in terms of number of users but also for higher data rate applications. The issue becomes the agenda of debate for both academia and industry around the world. This panel, which consists of international researchers from both industry and academia, will discuss various important issues related to 3G and beyond. Fourth Generation (4G) wireless communications systems have been proposed because of its difficulty of Code Division Multiple Access (CDMA) technologies to achieve higher data rates and therefore, satisfy continuously ever increasing demand for data rates and bandwidth to meet multi-media userNULLs requirements. With ever increasing in data rates, the output power of the air-interface must be increased and or the size of the cell has to be decreased to accommodate higher rates. These implementations introduce difficulties. 4G communications networks may require distributed architecture, End-to-End Internet Protocol (IP), and peer-to-peer networking. Coverage and Capacity could be adaptive and dynamically accommodate changes in userNULLs patterns. Users could move automatically away from the congested routes to allow network to dynamically and automatically self-balance itself. Panel discussion also addresses the issues of security in the mobile and wireless IP. IP is dominating the next generation mobile and wireless technologies. Its security is becoming a major concern.

This paper introduces and analyzes a field estimation scheme for wireless sensor networks. Our scheme imitates the response of living beings to the surrounding events. The sensors define their periphery of attention based on their own readings. Readings differing from the expected behavior are considered events of interest and trigger the data transmission to the sink. The presented scheme is evaluated with real-site-collected data and the tradeoff between the amount of data sent to the sink and the reconstruction error is analyzed. Results show that significant reduction in the data transmission and, as a consequence, in the energy consumption of the network is achievable while keeping low the average reconstruction error.

Anglais - 12 p - Abstract
This paper addresses the performance of geographical routing protocol in wireless networks, where only few nodes possess self-locating capability such as GPS. To be able to apply end-to-end geographical routing protocols, it is necessary every node know their position coordinates. We propose a method to infer such positioning information to any node, based only on connectivity and localization information obtained from the neighborhood. Three metrics are used to evaluate the performance of such a scheme : the density of useful nodes for geographical routing protocol, the reachability and the path length.

This document summarizes the work done during the first stage of Work Package 2 (WP2) (Seamless Service Delivery to the Nomadic User). The objective of WP2 is to specify an architecture allowing seamless service delivery across different wireless access networks and wired networks. To obtain this objective, in this first stage of the project, we elaborate a State of the art of terminal mobility in a heterogeneous network environment. The analysis is based on research publications, research projects and standards for an overall technology overview covering all lower network layers. Based on this study, some functional and operational requirements have been identified for the main issues relating on the WP2 (mobility management, roaming, interworking, security management and resource management). These requirements are the input for the basic architecture of SUMO (WP1).

Using WEP in Ad-Hoc Networks
WOCN06
Bangalore (India), April, 2006
Anglais - 4 p - Abstract
Nowadays, with the normalization of the 802.11 standard and the emerging of Wi-Fi low cost devices, many testbeds use this wireless technology to realize ad-hoc networks. The 802.11 security protocol, WEP, has not be designed by security experts. It results in a flawed protocol. The secret key shared between all 802.11 devices can be retrieved by attackers passively collecting data over the wireless network. TKIP, that solves this problem by periodically refreshing the keys between the access points and the wireless clients, has been standardized. But 802.11 ad-hoc networks remain unsafe. We address the problem of security in ad-hoc environments by using smart cards to handle the actual WEP-based 802.11 networking adapters to refresh the WEP key, like TKIP does in infrastructure environments.

In this paper, we introduce a Business Aware Framework for the Management of policy enabled IT Systems and its application to Utility Computing Environments. The framework couples two main subsystems on top of an IETF-like policy-based resource control layer. They are MBO (Management by Business Objectives) where the decision ability supported by analysis of business objectives resides, and GSLA (Generalized SLA), an advanced framework for SLA driven management that lends itself quite naturally to the derivation of IT management policies from the SLAs that the enterprise has contracted. We discuss the advantages and the limitations of the state-of-art policy-based approach to systems management, mainly the lack of business and service level context to drive policy-related decisions at system run-time. We then explain how this is remedied in our framework through the interaction mechanism between the reactive policy-based resource control layer and the more proactive business driven decision-making engine

WiMedia, Wi-Fi, WiMax, Wi-Mobile, WiRAN, the Wi-family is getting bigger; so does the network architecture. It is encouraging to see the fast development of the new IEEE wireless technologies promising the ultimate Internet service deployment on wireless and mobile infrastructures since they would offer larger bandwidth at cheaper price compared to the telecommunication wireless radio resource. However it is disquieting to see that the TCP/IP protocol stack which is supposed to be the heart of the Internet services deployment is not evolving as fast as the wireless technologies do. Here we come up with the hard question which is the network performance of the TCP/IP architecture over wireless networks. It is probably too early to decide to replace TCP/IP by another protocol stack for wireless network support, but it is important to not ignore the problem and analyse the main drawbacks of TCP/IP in wireless networks and think about a new architecture of network communication over the wireless networks. This paper provides a brief survey of what we name here the Wi-family wireless technologies, and emphasizes on new network architecture to optimize the TCP/IP behaviour worsen by the wireless characteristics.
