Multicast Fast Handover Algorithm Based on Neighbor Information Exchange
基于邻居信息交换的组播快速切换算法

The handover latency and the packet loss rate are important criterions that determine if the mobile multicast algorithm could adapt to real-time multicast appliances.This paper proposes a multicast fast handover algorithm based on neighbor hood information exchange(M-FMIPv6/NIE).Before L2 trigger event occurs, M-FMIPv6/NIE can configure new care-of-address(nCoA)and request new access routers(AR)to join multicast tree.The performance analysis and simulation results indicate that,the multicast service disruption time of M-FMIPv6/NIE is less than that of existing multicast fast handover algorithms and it has good performance in buffer size and packet loss rate.
