Abstract

LEO satellites’ low altitude from the ground, short movement period, fast speed and high link topology reconstruction frequency cause a certain decline in its communication performance. Therefore, the topology construction strategy of LEO inter satellite links (ISLs) has attracted great attention. At present, there are few topology construction technologies for LEO ISLs in mixed orbit scenarios internationally, and there are limitations such as limited topology stability and few control mechanisms to extend the terminal life of intersatellite links. Aiming at reducing the constraints of mixed orbit LEO satellite ISL communication in the actual situation, the research on LEO satellite topology construction technology based on multi-objective optimization algorithm is carried out. For the stability of satellite connection topology, the energy consumption in network, and the average transmission delay between satellite nodes, the three indicators with mutual constraints are optimized, and compared with other connection methods to verify its advantages.
