Research on Multi-Orbit Hybrid Satellite Network Routing Algorithm Based on Detection and Self-Learning

摘要

With the rapid development of commercial space program, the constellations of low-orbit satellites continue to emerge. The use of satellite networks and terrestrial networks to construct a space-ground integrated network and provide users with seamlessly connected communication services has become a trend in the future. Due to the relative motion characteristics of satellites, existing routing technologies such as routing algorithms based on rule-based network topology can no longer meet the requirements for routing calculation in such a dynamic network topology. Based on the analysis of the routing strategies of existing typical satellite networks and the characteristics of satellite operation, this paper illustrates a multi-orbit hybrid satellite network routing algorithm based on detection and self-learning. The algorithm has a simple control process with high reliability. The simulation results show that the protocol has good network performance in terms of effective data transmission rate and data routing hops, and can support the design of routing protocols for multi-orbit mixed satellite networks.
