Video Multicast Over Wireless Ad Hoc Networks

Free registration required

Executive Summary

Existing video multicast routing protocols in wireless ad hoc networks have been developed under the assumption that destination nodes wish to receive all the information sent by the multicast source, i.e., they do not support heterogeneous destinations. This paper addresses the problem of video multicast for heterogeneous destinations in wireless ad hoc networks. Multiple Description Coding (MDC) is used for video coding. MDC generates multiple independent bit-streams, where the multiple bit-streams are referred to as Multiple Descriptions (MD). Furthermore, MDC enables a useful reproduction of the video when any description is correctly received.
