摘要
针对现有移动IPV6中数据包发送代价较高的问题,对现有移动IPV6协议性能分析模型中数据包发送路径进行了改进,将访问路由发送至移动节点的数据包由代价很大的隧道发送改进为直接发送,避免了隧道代价因子对数据包发送代价的影响。同时分析对比了移动IPv6协议MIPV6、FMIPV6、HMIPV6和PMIPV6在现有模型下和改进数据包发送路径模型下的数据包发送代价和切换时延、吞吐量。理论分析与实验仿真表明:现有移动IPv6协议在改进数据包发送路径模型下的数据包发送代价和切换时延比在现有模型下低,吞吐量有所提高。该改进数据包发送路径模型适合应用于数据包传输速率较高的场合。
Focusing on the problem that high packet delivery cost of the existing mobile IPV6 protocols, a performance analysis model is modified, in which the packets delivery from the AR to the MN is modified into direct delivery, and the tunneling cost factor is avoided .Then the packets delivery cost , handoff latency and throughput are compared in the present performance analysis model and the modified one for the present IPV6 protocols including MIPV6,FMIPV6,HMIPV6 and PMIPV6. Finally, the theoretical analysis and simulations results show that the present IPV6 protocols show less packet delivery cost , less handoff latency and higher packet throughput in the modified mode than in the present mode, which is suitable for higher packets delivery rate demand applications.
