A fast dynamic multicast tree adjustment protocol for mobile IPv6

摘要

Internet research community has proposed many Different multicast routing protocols to support efficient multimedia application such as, IPTV, videoconferencing, group games. Nevertheless, these protocols have not been designed for mobile roaming members and sources, and has not been tested in wireless and mobile environment since they were developed for multicast parties whose members and sources are topologically stationary. Recently, as the performance of mobile hosts rapidly improves and the bandwidth of wireless access networks grows up, the expectation for mobile multimedia communication services including many-to-many communications such as video-conferencing begins a big necessary. Studying and solving multicast issues in the stationary multicast infrastructure has been largely studied in the literature. However, fewer efforts have been spent in the specific problems of mobile members and sources caused by the frequent change of membership and point of attachment. This paper addresses the issue of mobile Multicast routing by presenting a Fast Dynamic Multicast Tree Adjustment Protocol for Mobile IPv6 (FDMTA-MIPv6), an optimized multicast tree protocol is proposed to transform multicast tree into an optimal shared multicast tree routed at a selected RP. To estimate and evaluate our scheme, we implement simulation based in many metrics, simulation results show that good performance is achieved in terms of handoff latency, end-to-end delay, tree construction delay and others metrics.
