摘要

基于IP的移动性管理技术使得移动终端可以在互联网间漫游

并且不会改变自己的IP地址.当同时存在多种类型无线网络的时候

如何选择最佳的候选网络

何时发起切换等切换判决问题也是提高基于IP的移动性管理性能的重要课题.提出了一种基于位置信息的切换判决算法

使得终端在对自身移动模型预测的基础上

做出正确的切换目标和切换时间的选择

从理论分析和仿真结果可以看出

该算法明显减小了切换次数和丢包率

提高了切换的性能.

Abstract

IP based mobility management scheme makes mobile host roaming in heterogeneous network without changing its IP address.How to select the best candidate network and when to make handoff have a strong effect on performance of mobility management.This paper proposed a location information based handoff decision algorithm.MH can select right candidate access router and make handoff in best occasion.Theoretical analysis and simulation show that number of handoff and packet loss rate can be decreased.
