摘要： 以基于卫星移动通信的网络移动方案为研究背景，将网络仿真软件NS作为仿真平台，扩展和改进NS中移动IPv4的相应模块，设计并实现双重IP隧道，使其支持拓扑固定的网络移动功能。通过改进无线信道的相应模块完成对卫星信道的模拟，建立可以对IP业务传输性能进行仿真、基于卫星移动通信的网络移动模型BMSC-NEMO，仿真实验验证了模型的有效性和准确性。

关键词: 卫星移动通信, 网络移动, 隧道

Abstract: Under the research background of the network mobility based on mobile satellite communication, using the network simulation software NS as the simulation platform, by extending and improving the module of the Mobile IPv4 model in NS, this paper realizes the double IP tunnel, which can sustain the function of NEtwork MObility(NEMO) with fixed topo. By improving the module of the wireless channel, the satellite channel is simulated, the BMSC-NEMO model based on mobile satellite communication which can simulate the transmission performance of IP data is built, and the validity and veracity of the model is validated by simulation experiment.

Key words: mobile satellite communication, NEtwork MObility(NEMO), tunnel
