Multipath Video Communication In Wireless Ad Hoc Networks

摘要: In this work, we introduce new path diversity schemes in order to provide robustness for both unicast and multicast video communication applications over wireless ad hoc networks. We first propose a general architecture multipath streaming Then the case, with two node-disjoint paths, which have minimum concurrent Packet Drop Probability (PDP) among all pairs. This approach minimizes probability of loss descriptions, thus optimizing worst case Multiple Description Coding (MDC) quality times. Based on our selection model, heuristic PDP aware routing protocol. For multiple tree MDC. Specifically, distributed protocols, Serial Disjoint Tree Multicast Routing (Serial MDTMR) Parallel Nearly-disjoint Trees (Parallel MNTMR). show o f proposed protocols are significantly higher than that other through extensive NS simulations actual experiments.
