| 摘 要： | 针对低轨卫星星座通信系统动态拓扑结构的特点，提出了一种基于反向探测的路由算法（Reverse Detection Based Routing，RDBR），采用分布式实现且具有极低的运算复杂度，适合于星上实时计算，对于提高星座网络的自主运行能力具有重要意义。与快照序列（Sequent Snap Shots，SSS）算法的对比分析和仿真表明，RDBR算法以有限的信令开销取得的路由性能优于60s快照序列算法。

| Abstract: | Based on the dynamic topology of the Low Earth Orbit satellite constellation networks,a novel routing algorithm named as the Reverse Detection Based Routing(RDBR) is proposed.It is a distributed algorithm with very low computational complexity,so it is very suitable for the On-Board-Processing and also important to improve the constellation network capability of autonomous operation.The analysis and simulation results show that with acceptable low overhead signaling,the RDBR algorithm can achieve better per... |
