Cross-Layer Design for Quality of Service Multicasting in Mobile Ad Hoc Networks

In Mobile Ad hoc Networks (MANETs), the issues of connectivity, bandwidth, link stability and route failure tolerance significantly affect multicasting. This research work investigates these key issues using graph theory concepts. Further, route failure-tolerant and stable multicast paths are computed based on the graph theory metric called Connectivity Index (CI). This investigation has resulted in Cross-Layer Design (CLD) of QoS multicast protocol based on MPEG-21 multimedia framework. The research work is carried out in MATLAB environment.
