    • 摘要: 低轨卫星通信系统在通信领域发挥着越来越重要的作用。针对不同类型星座覆盖能力和星际链路建立条件存在的差异,设计了极轨道和倾斜圆轨道低轨卫星星座,利用STK验证了两种星座的覆盖能力和星际链路AER特性,利用NS2对两种星座卫星网络的时延、吞吐量和丢包率等性能指标进行了仿真,并对所得数据进行了对比分析,结果表明:在由32颗卫星(轨道高度1450 km )构成的低轨星座中,极轨星座的全球覆盖能力、星际链路建立条件和卫星网络性能优于倾斜圆轨道星座,更适合于构建全球低轨卫星通信系统。%LEO satellite communication weighs more and more in communication system now and future .Since different types of constellations have rather different performances in coverage ability and inter-satellite link building conditions ,a polar and an inclined circular orbit constellation were designed in this paper .Coverage ability and ISL performance of con-stellations were simulated by STK while delay ,throughput and jitter of satellite network were simulated by NS2 .The results of simulations were compared and analyzed which indi-cates that ,in a constellation with 32 satellites ,with orbit altitude 1 450 km ,polar orbit con-stellation is more suitable to build global LEO satellite communication system than inclined circular orbit because of its nicer performance in global coverage ,ISL building conditions and network identity .

    • 摘要: The structure and characteristics of the multilayer satellite network is studied in allusion to the problems of single satellite network such as long time-delay, high snarl-up rate. In order to solve the problem as constrains of satellite performance in single orbit, structure of layered satellite network is introduced combined with the features of satellites in different orbit heights, and a constellation of multilayer satellite network is designed by walker and coverage band of polar-orbit. As the redundancy in strong-connect model is too high, the weak-connect model is introduced as the basic principle of ISL foundation. The coverage rate of the constellation and the identity of ISL are simulated and analyzed, the result indicates that the multilayer satellite network has more advantages on coverage ability and ISL identity.%针对单层卫星网络时延高、网络阻塞概率大等问题,研究了多层卫星网络的系统结构及其特点.为解决单一轨道对卫星性能发挥的限制问题,结合不同轨道卫星特点,引入分层卫星网络结构,采用Walker和极轨星座覆盖带设计法,设计了多层卫星网络星座.针对“强连接”模型中星际链路冗余度过高的问题,采用“弱连接”模型作为星际链路建立的基本原则,并对星座的覆盖性能和星际链路特性进行了仿真分析,结果表明,多层卫星网络在覆盖特性和星际链路性能上更具优势.

    • 摘要: A novel link-reconfiguration algorithm is proposed to solve the problem that the transfering delay increases caused by failed Inter-Satellite-Links linked with fail satellites in Space Network. The algorithm limits the connectivity degree of nodes, guarantees minimum link delay, and rebuilds the links affected by fail satellite nodes. The article constructs network topology and the whole link-reconfiguration process by STK simulation software, and then completes performance simulation of the algorithm by OPNET simulation software. The result from the simulation has shown that the novel link-reconfiguration algorithm reduces the end-to-end link delay in Space Network, thus, keeps Space Network stable.%在空间网络中,为了解决与故障卫星节点相连的星间链路失效而导致的传输延时大幅增加问题,提出了一种新的链路重构算法.该算法在对节点连接度上限约束的同时,保障了链路延时最小,进而完成了受故障卫星节点影响的链路的重建.利用STK仿真软件构建了网络拓扑及链路重构过程,进而利用OPNET仿真软件完成了算法的性能仿真验证.仿真结果表明,使用新链路重构算法减小了空间网络的端到端链路时延,从而保证了空间网络的稳定性.
