网络的移动性是基于移动IPV6的，但在这个领域还没有非常适合的模拟工具。NS2是一个常用的网络仿真软件，而且随着NS2中的一个叫“Mobiwan”补丁出版，它已经可以仿真移动IPV6。基于NS2和Mobiwan，一个针对网络移动性的扩展计划被提出。对该计划的若干问题进行分析，这些问题中的一些关键技术被提出。在本文中对该扩展的有效性进行了测试与验证。-Network mobility is based on the mobile IPV6, but not in this area is very suitable for the simulation tool. NS2 is a commonly used network simulation software, and along with a NS2 called " Mobiwan"　patch publishing, it has to simulation mobile IPV6. Based on the NS2 and Mobiwan, a mobile network expansion plans have been put forward. The plan to analyze a number of issues, these issues have been raised a number of key technologies. In this article the validity of the expansion of testing and verification.
