摘要
通过对分层移动路由协议的分析,提出一种优化的移动路由机制.利用分层移动IPv6的路由特点可以减少网络通信中绑定更新消息发送的距离和数量,从而减少网络中的信令负载和绑定注册时延.同时,又利用快速切换的优势,在切换中引入适当的并行操作,从而消除标准MIPv6切换时的大部分时延和丢包率,通过引入边界路由器实现路由优化和解决移动锚点MAP的拥塞问题,最后通过理论性能分析和NS2仿真实验验证该优化移动路由可以改善网络性能,降低丢包率和切换时延.
This paper analyzes the hierarchical mobile routing protocols, and puts forward a new optimized mobile routing protocol. By using hierarchical mobile IPv6, the new protocol can effectively reduce the distance and the number of binding update message to send, so as to reduce the signaling load and the delay of binding registration in the network. At the same time, by using fast switching and parallel operation in the fast switching, most of time delay and packet loss rate of the standard MIPv6 can be eliminated. By using the edge router, it can optimize routing and solve the problem of congestion of the MAP. Finally, through the analysis of theoretical performance and the verify of the simulation experiments in NS2, it shows that the new optimized mobile routing can improve the performance of the network, reduce the packet loss rate and handover delay.
