摘要： 在分级移动IPv6(HMIPv6)中，MAP选取的不合理往往会造成移动节点(MN)通信服务延时增加和MAP负载过于集中。该文综合考虑了MN的移动速度、移动轨迹等因素，提出一种新的基于MN移动特征的MAP选择算法。仿真结果表明，该算法能够根据MN 的运动特征和网络当前拓扑结构特点来选取移动代理MAP，有效地降低了MN的服务延时，更合理地利用了HMIPv6网络中的MAP资源。

Abstract: There are the problems of Mobile Node(MN) communications services delay increasing and load convergence in Hierarchical Mobile IPv6 (HMIPv6) for the unreasonable selection of MAP. A new MAP selection algorithm according to MN movement characteristics is proposed based on the comprehensive account of the speed, mobile track and other factors of MN. Simulation results show that the MAP selection algorithm can optimally select the MAP for different mobile nodes, reduce the communication delay of MN.

Key words: delay, Mobile Node(MN), track
