An Optimized Layered Routing Algorithm for GEO/LEO Hybrid Satellite Networks

Data transmission through satellite networks provides ubiquitous communication all over the world. But the time-variant topologies lead to lossy inter-satellite links and long end-to-end delay. To address these problems, in this paper we propose a novel satellite network management method and routing algorithm. The former specializes satellites in different layers to utilize network resources efficiently, and the latter is an optimized layered routing algorithm based on TORA and Dijkstra's algorithms. The proposed algorithm is customized for the hybrid GEO/LEO satellite networks and aimed at balancing between data traffic and end-to-end delay.
