基于多隧道的MIPv6快速切换改进方案

摘要

On the basement of research on the Fast handover for Mobile IPv6 protocol(FMIPv6), this paper proposes an improved scheme of fast handover which is based on multi-tunnel.Through improvement of the fast handover procedure and introduction of the tunnel status and life cycle management mechanism, this scheme can avoid forecasting the handover information of mobile node, decrease the effects caused by the moving speed of mobile node and reduce the spending of signaling that is from ping-pong movement.Simulation results show that the fast handover scheme based on multi-tunnel has good performance.%在研究移动IPv6快速切换协议的基础上,提出一种基于多隧道的快速切换改进方案.该方案通过改进切换流程,引入隧道状态和生存期管理机制,避免预测移动节点的切换信息,同时降低移动节点运动速度对切换造成的影响,减少因乒乓运动带来的信令开销.仿真实验表明,基于多隧道的快速切换方案具有较好的切换性能.
