Heuristic Inter-Satellite Routing Algorithms for Dense Low Earth Orbit Constellations
摘要
Abstract
Inter-satellite links play a critical role in determining the communication performance of dense low Earth orbit constellations,where routing algorithms based on link connectivity are essential.To enhance the performance of inter-satellite communication,a heuristic inter-satellite routing algorithm is developed using Python.This algorithm optimizes the trade-offbetween path cost and end-to-end delay under dual constraints of path bandwidth and maximum tolerable delay.By dynamically integrating genetic algorithms with ant colony optimization,the global optimal convergence process is accelerated,and the stability of the algorithm is improved.Simulations based on Starlink constellation parameters validate the superiority of the proposed heuristic inter-satellite routing algorithm.关键词
