Predictive resource allocation in multimedia satellite networks

Unlike terrestrial networks, LEO satellite networks are expected to provide a truly global coverage and to support sophisticated PCS services including multimedia communications. However, LEO satellite networks are known to have a serious mobility management problem. The main contribution of this work Is to propose a predictive handoff management and admission control strategy for multimedia LEO satellite networks. Simulation results have shown that our scheme offers very low call dropping probability for multimedia connections while, at the same time, keeping resource utilization high.
