基于OPNET的低轨卫星网络仿真平台

OPNET Based Low Earth Orbit Satellite Network Simulation Platform

为研究适用于低轨卫星网络的协议与算法,在OPNET中搭建仿真平台,包括卫星网络拓扑的设计、节点模型、进程模型以及链路模型的建立。该平台能模拟低轨卫星网络路由表的建立和数据包选路等过程。依据卫星网络运动的规律性,采用拓扑快照方式的静态路由策略,对低轨卫星网络进行路由仿真,验证了平台的有效性。

To study protocols and algorithms for Low Earth Orbit（LEO） satellite networks, a platform is built based on OPNET. The platform introduces the key points including topology design, node models, process models, link models and etc. It can simulate the procedures of routing table generation and packets routing in LEO satellite networks. Since satellite networks run regularly in the space, topology snapshot based static routing strategy is adopted, packets routing is simulated in an example satellite network, and the validity of the platform is proved.
