Supporting Video Multicast in Wireless Ad Hoc Networks Using Multiple Paths and Multiple Description Coding

Multiple Description Coding (MDC) generates multiple independent bit-streams, where the multiple bitstreams are referred to as MD (multiple descriptions). Moreover, MDC enables a useful reproduction of the signal when any description is received correctly. In this paper, a heuristic multicast algorithm that exploits this salient property of MDC along with multiple disjoint paths for improving the user’s satisfaction for a group of heterogeneous destinations in wireless ad hoc networks is proposed. Simulation results demonstrated the effectiveness of the proposed algorithm in improving the user’s satisfaction irrespective of the number of destinations in the multicast group.
