文章在分析卫星接入网系统体系结构的基础上,将移动IP技术应用到系统中有关移动用户路由寻址问题上,并对标准移动IP进行改进。通过对三种路由方案的对比分析及利用NS2仿真结果表明,基于中间移动代理的路由优化方案在卫星网接入系统中具有一定的实用价值。
On the basis of analyzing the architecture of satellite access network system, this paper applies Mobile IP technology to the routing problem of mobile subscribers in the system, and improves the standard mobile IP. Through the comparative analysis of the three routing schemes and the use of NS2 simulation results, it shows that the routing optimization scheme based on the intermediate mobile agent has certain practical value in the satellite network access system.
