摘　　要：近年来,在低轨(LEO)卫星星座通信网络中采用网际协议(IP)路由算法的研究已经取得了一系列进展,文章论述了LEO星座通信网络的特点、拓扑结构和虚拟节点策略。在此基础上提出了基于泛洪路由的LEO星座动态源路由算法DSR-LSN(Dynamic Source Routing algorithm in LEO Satellite Networks),星座网络仿真表明,DSR-LSN算法具有网络路由状态稳定性好、时延小的优点。Several IP-based routing algorithms have been developed for low-earth orbit(LEO) satellite networks in recent years.In this work,we firstly introduce the characteristics of LEO satellite networks and the Virtual Nodes' concept in this network.Based on these introduction,a new Dynamic Source Routing algorithm in LEO Satellite Network,DSR-LSN,is developed.The performance of the DSR-LSN algorithm is evaluated through a simple LEO satellite constellation network model and analysis.Through the evaluation of perf...
