摘　　要：在层次化移动Ipv6协议中,当CN和MN位于同一个MAP域时,两者之间的通信不是优化的路由,可以将MN的链路转交地址通知给CN,实现在移动节点和通信对端之间直接通信,达到路由优化的目的。当移动节点频繁切换时,导致了绑定更新开销的增加。切换频率和数据报传送频率是路由优化研究要考虑的两个重要因素。在权衡考虑MN的切换频率和数据报传送频率的基础上,提出了一种自适应的局部路由优化方案,并分析了该方案的性能。仿真结果表明,在较大的SMR范围内,该方案具有较好的性能。When a correspondent node （CN） and the mobile node （MN） are located in the same MAP domain, a non-optimized route is formed in hierarchical mobile IPv6 （HMIPvt）. In this case, a route is optimized by informing the CN of the MN＇s LcoA. Then the CN and MN correspond direct. This optimization result in a higher BU cost when the MN hands off frequently. Therefore the mobility and the packet delivery are key factors to the research of route optimization. To balance the trade-offbetween the binding update cost and route optimization, an adaptive local route optimization （ALRO） is presented and the performance of the scheme is analyzed. The simulation results show that the ALRO scheme has a better performance in a wide range of SMR.
