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...
Large-scale deployment of multicast applications is limited by the number of states that are set in routers for multicast groups. Aggregation is a natural solution to reducing the multicast forwarding states. In the way of sharing a common distribution tree among several groups, the approach to aggregated multicast reduces the number of forwarding states and improves network performance. Finding the...
In this paper, we address the issue of multilayered multicast routing in wireless ad hoc networks (WAHNs). Existing multilayered multicast protocols assume homogeneous ad hoc wireless networks; in which all nodes are of the same type (they have the same processing, data rate and communication capabilities and characteristics). A more realistic assumption is a heterogeneous network; in which nodes...
