Research of Routing Techniques in Satellite Networks with ISLs

With the rapid development of Internet applications, the IP-based data services will continue play an important role in the global information infrastructure (GII). Satellite networks can provide global coverage and support a lot kind of services. Packet routing in satellite networks with inter-satellite links becomes a very challenging problem to provide fast data transmission. In the last couple of years, various routing algorithms and protocols have been proposed, the goal of which is to find optimal path and achieve some kind of quality of service. In this paper, the difficulties of routing in satellite networks are analyzed, and a survey of all kinds of existing routing algorithms and protocols, which are compared in detail, is presented. At the same time, some personal prospective of further research and some challenging open problems are identified.
