| 摘 要： | 文章结合LEO卫星网络的拓扑结构和运行规律，提出了一种时延受限的最小耗费（DCLC）路由算法。仿真结果显示，相对于最短路由算法，该算法具有较低的呼叫阻塞率和切换失败率，以及更好的服务质量。同时能够平衡各链路负载，使整个卫星网络更稳定。

| Abstract: | Combined with the topologies and operating rule of LEO satellite networks, a time-delay and least cost route algorithm is proposed. The simulation results showed that the proposed algorihm has lower call backup ratio,lower switching failing ratio and better QoS compared with the shortest route algorihm. Moreover, the algorithm can also balance each link load to make all satellite networks more stable. |
