| 摘 要： | 研究了空间信息网络的拓扑结构和路由特点，对网络的里间链路长度和覆盖性能进行了分析。针对空间信息网络的特．最对现有算法进行了改进，并加入一些优化措施。从而形成一种新的适用于空间信息网络应用的动态路由算法，谊算法能够找出任意两颗卫星间通信的最佳路径集合，同时能够在链路质量容许的情况下，尽量避免通信链路切换的发生，从而较大地提高了系统性能。通过仿真和分析表明谊算法提高了系统性能，降低了切换概率，增加了链路的可靠性，且相对付出的链路代价较小。

| Abstract: | In this paper,it studied the topology architecture and routing characteristics of the spaceinformation network,then the length of ISL(inter satellite link) and performance of coverage areanalyzed.It i mproved the algorithmfor the characteristics of space information network and madesome opti mizing ways.Then it proposed a new routing algorithm applied for space informationnetwork.The newalgorithmcanfindthe aggregate of best communicationroutes between anytwosatellites,and can reduce link switching as much as possible,thus the systemperformance is i m-proved.Analysis and si mulation results showthat the newrouting algorithmcan enhance the per-formance of the network,and increase the link reliability,on the other hand,it costs very littlelink requirements. |
