Multiple Description Coding Based Video Multicast over Heterogeneous Wireless Ad Hoc Networks

In this paper, we investigate how Multiple Description Coding (MDC) can improve the user´s satisfaction for a group of heterogeneous destinations for video multicast over wireless ad hoc networks. Specifically, we explore the independent-description property of MDC with multiple paths to improve the user´s satisfaction. In our approach, the assignment of multiple description (MD) video is randomly done by a multicast source node. Based on the assignment of MD video, the multicast source constructs multiple multicast trees accordingly. Simulation results demonstrate that our approach can achieve higher user´s satisfaction regardless of the multicast group size.
