PMIPv6域中基于扩展信令的网络移动性优化方法

摘要

In order to resolve the problem of huge total cost caused by supporting NEtwork MObility (NEMO) in Proxy Mobile IPv6 domain,a NEMO optimization solution based on extending signaling is proposed.With the help of extending signaling message,the integration between location update and forwarding packets,this solution evenly reduce the location update overhead and packet tunneling overhead.Analysis and simulation show that,the solution can reduce tocal cost.%针对PMIPv6域中支持网络移动性存在的总开销过大问题,提出一种基于扩展信令的网络移动性优化方法.利用扩展的信令消息,整合位置更新和转发数据过程,均衡降低了系统的位置开销和隧道开销.性能分析表明,相比传统机制,本方案有效降低了系统总开销.
