Abstract

In low earth orbit (LEO) satellite communication systems, frequent intra- and inter-satellite communication handoffs are caused by the high-speed relative motion between the Earth and the satellite. Then frequent handoffs lead to a great call dropping probability which is a main parameter for system's QoS. In this paper, a Genetic Algorithm (GA) based adaptive bandwidth allocation scheme is presented. Aiming at multi-services satellite systems, the scheme focus on the system's QoS which is expressed by the customers' satisfaction degree and handoff call dropping probability. The effectiveness of the scheme is proved by simulation results.
