针对低轨卫星星座高动态拓扑导致的路由链路切换频繁、回传时效性差问题,本文提出基于走廊约束与简化常规摄动模型4(simplified general perturbations 4
SGP4)轨道预测的低轨星座路由优化算法。算法构建走廊约束模型压缩路由搜索空间,利用SGP4预测链路可用性,综合时延、跳数与链路稳定性构建多目标代价函数选取最优路径,并提出预测式切换策略。以“鸿雁”星座与BDS-3异构星座为对象,与Bellman-Ford和MADRL算法对比仿真,结果表明传输时延分别降低30.5%~30.8%和36.2%~39.3%,路由跳数分别减少27.7%~29.1%和42.5%~46.9%,路由可达率均超过97%,验证了算法在低时延、高效率与鲁棒性方面的优势。
To address the issues of frequent routing link switching and poor backhaul timeliness caused by the highly dynamic topology of LEO satellite constellations
this paper proposes a routing optimization algorithm for LEO constellations based on corridor constraints and SGP4 orbit prediction. The algorithm constructs a corridor constraint model to reduce the routing search space
utilizes SGP4 to predict link availability
and constructs a multi-objective cost function that integrates delay
number of hops
and link stability to select the optimal path. Using the “Hongyan” constellation and the BDS-3 heterogeneous constellation as test cases
simulations were conducted in comparison with the Bellman-Ford and MADRL algorithms. The results show that transmission delay was reduced by 30.5%~30.8% and 36.2%~39.3%
respectively
with the number of routing hops reduced by 27.7%~29.1% and 42.5%~46.9%
respectively. The routing reachability rate exceeded 97% in both cases
validating the algorithm’s advantages in terms of low latency
high efficiency
and robustness.
