| 摘 要： | 针对具有星际链路的LEO/MEO卫星网络,设计了一种具有自主运行能力的卫星网络动态路由协议(SDRP).采用时间离散化的链路状态增量更新的虚拟拓扑路由算法,降低了网络开销.提出的多点转发节点选举算法,提高了路由收敛速度和网络资源利用率.仿真结果表明,卫星网络动态路由协议的路由收敛时间远小于网络稳态保持时间,路由收敛时间是OSPF的1/10,平均协议带宽占用率也大大小于OSPF,可以保证卫星网络的信息可靠传送.

| Abstract: | A Satellite Dynamic Routing Protocol(SDRP) with autonomy is proposed for the low earth orbit/medium earth orbit satellite networks with inter-satellite links.The Discrete-time link state Incremental Virtual Topology Routing Algorithm is used to reduce the network overhead.The Multicast Forwarding Node Election Algorithm is put forward to enhance both the routing convergence speed and network resource efficiency.The simulation results show that the routing convergence time of the satellite network dynamic ro... |
