基于云存储的改进HMIPv6域内切换研究

Research on Improved Intra-domain Handover in HMIPv6 Based on Cloud Storage

针对HMIPv6切换过程中大量信令交互行为引起切换时延大的问题,提出了一种改进的域内切换方法.该方法通过引入云存储服务器功能实体,实现了对转交地址的管理,降低域内网络节点负载,减少了网络信令代价.结果表明,该方法有效地缩短了切换时延.

Aiming at the problem of handover delay,a new method was proposed. Signal exchange was happened in hierarchical mobile IPv6 protocol,which caused latency. A new entity is introduced named cloud storage server （CSS）to manage care-of address list. The load of node in intra-domain networks was reduced, and the cost was lessened. The experimental results show that the improved method can effectively shorten the handover delay.
