在本文中，我们分析了两个重要的移动管理协议的性能。。MIPv6和HMIPv6。为计算信令成本，建立了随机行走和流体流动两种移动性模型的分析模型，该模型由位置更新成本和分组传递成本两部分组成。
English Description：
In this article, we analyzed the performance of two important mobile management protocols.. MIPv6 and HMIPv6. To calculate the signaling cost, two mobility models, random walking and fluid flow, were established for analysis. The model consists of two parts: position update cost and group transfer cost
