本文正是在研究WIMAX/802.16e协议和FMIPv6协议的基础之
上,提出了基于FMIPv6的WIMAX网络快速切换机制,该方案采用跨
层切换的思想,MAC层联合网络层同时进行切换,在链路尚未断开
之前即完成新转交地址(NCOA)获取等功能,从而加快了切换进程,
减小了切换时延和切换时的丢包率。在提出本切换机制的基础上,本
文在NSZ仿真平台上对所提出的切换方案做了系统性的性能仿真,通
过仿真结果验证了方案的可行性和优越性。

Abstract: By analyzing the source codes of ns-2, we discuss the simulated implementations of
wireless channels, network interfaces and mostly the 802.11 MAC protocol in ns-2. We also notice
the “bugs” of the 802.11 simulation compared with the re
