A Satellite Routing Algorithm Based on Optimization of Both Delay and Bandwidth

The merits of the routing algorithm will have a direct impact on the performance of a communication network. Traditional satellite routing algorithms are based on shortest path algorithm, the simply considering least delay, the least hop or the best link-bandwidth utilization. For the request of real-time in information network, a routing algorithm BDSR (bandwidth-delay satellite routing) comprehensively considering both delay and bandwidth between satellite-link is proposed in this paper. Moreover, we prove that the routing algorithm is an ideal one that is suitable for LEO satellite network on NS2 simulation platform.
