摘　　要：HMIPv6引入移动锚点(MAP)实现局部绑定更新。通常需要根据网络规模部署多层MAP为移动服务提供更好的扩展性和鲁棒性,但也引入了额外的数据包处理与传输开销,因此为移动节点选择最佳服务MAP仍是关键问题。通过对目前主要的服务MAP选择技术及方法的调研和分析,实验选择了三种典型的MAP选择方案:Further-based、Velocity-based及SMR-based作为比较对象,并设置了三种实验场景,比较分析了各方案在系统开销、平均切换时延方面的性能表现。The MAP is introduced in HMIPv6 to achieve local banding updating. Multi-level MAP architecture is usually employed to provide better scalability and robustness for the mobility in terms of the network size, the additional packets processing and transmission costs. Hence, selecting an optimal serving MAP for the mobile node remains a significant challenge. The recent representative developments and methods for selecting serving MAP are firstly discussed in detail, and then three typical MAP selec- tion mechanisms： Further-based, Velocity-based and SMR-based are selected for the comparison in the experiments, and three sce- narios are elaborately designed to compare and analyze the performance of system cost and average handover latency for the three MAP selection mechanisms.
