Research on Routing Algorithms of Satellite Communication System with Hybrid Orbit

Routing algorithms of satellite communication system with hybrid orbit are studied. The system consists of LEO and GEO satellites. "The longest covered-time" and "the shortest path" routing algorithms are proposed, which are analyzed and simulated. Route reconstructed rate and datagram loss rate are compared for the two algorithms. The results indicate that "the longest covered-time" routing algorithm can improve the system performance compared with "the shortest path" one.
