| 摘 要： | 通过对分层移动IPv6机制的分析,发现在切换时延和分组丢失率性能方面:当发生微观移动时得到了很大的改善;当发生宏观移动时,性能并没有改变. 针对以上问题研究了一种基于多播技术的分层移动IPv6模型. 在分层移动IPv6的基础上,扩展了路由器周期性通告的包头格式,给出了切换过程的具体操作过程,实现了移动节点的平滑切换,减小了宏观切换过程中的时延. 最后应用网络仿真软件NS-2对扩展的方案进行模拟分析,仿真的结果比较令人满意.

| Abstract: | Based on the analyses of hierarchical mobile ipv6 mechanism,it is known that this scheme has been improved in micro handover,but has no change in macro handover in handover delay and packet loss rate.The paper mainly discusses hierarchical mobile IPv6 based on multicast.The thesis is based upon HMIPv6 scheme,extends message format of router advertisement,implements every operation procedure in handover,discusses safety strategy of extended protocol,achieves seamless handover,decreases delay in macro handover.The author simulated the proposed scheme with network simulator 2 software and has obtained satisfactory outcome. |
