Abstract
Compared with Geostationary Orbit (GEO) satellite systems and Medium Earth Orbit (MEO) satellite systems, Low Earth Orbit (LEO) satellite systems provide lower propagation delay as well as higher throughput. Because of these reasons, LEO satellite systems can play a pivotal role in providing services to areas where there is no substantial terrestrial infrastructure. In this paper, a novel kind of Dynamic On-demand Multipath Routing algorithm (DOMR) is proposed for LEO satellite networks. The performance of LEO satellite networks based on DOMR algorithm is simulated and analyzed. Moreover, the packet delivery ratio of LEO satellite networks when running DOMR and Dynamic Source Routing Algorithm for LEO Satellite Networks (DSR-LSN) is compared. The packet delivery ratio is about 6.39% higher when running DOMR. Simulation results show that on-demand multipath routing algorithm has a good performance in drop rate and the end-to-end delay of packet delivery.
