A New Static Routing Algorithm of GEO/LEO Hybrid Satellite Networks

With the rapid development of satellite mobile communication, building a satellite/terrestrial integrated network is the inevitable trend of satellite communication. Based on the network of backbone and access, a global coverage of GEO/LEO hybrid satellite constellations are designed. As the backbone network, GEO constellation realize relay and management. As the access network, LEO constellation realize the communication with the terrestrial users. A new static routing strategy based on virtual topology is proposed, which provides significant advantages of low complexity, high efficiency and low routing overhead. The satellite networks can provide the features of flexible structure, easy management, efficient transferring, and potential in scalability.
