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).
