摘要
针对空间容延迟网络高动态拓扑、节点分布稀疏、链路频繁中断以及终端节点随机移动的特点,提出了一种适用于空间网络的SRM路由算法。该算法利用概率和存储转发机制,以解决终端节点随机移动路由问题为目标,依据各路径的连通时序图及节点相遇概率信息,最终确定链路的有效路径。理论分析和仿真结果表明,SRM路由算法具有良好的性能,适合在空间容延迟网络中应用。
Duo to its characteristics such as high dynamic topology,sparse distribution of nodes,frequent link interruption and terminator node random motion,a routing algorithm resolving terminator node random motion is proposed. To solve the routing problem of the random motion,the algorithm utilizes probability calculation and store-and-forward mechanism. In accordance with the intermittent connectivity phases of the routes and the information on node encounter probabilities,the available path is identified. Theoretical analysis and simulation results show that SRM achieves good performance and is suitable for spatial satellite network application.
