Abstract

The design of efficient radio resource management (RRM) strategy has become a key technique for the next-generation wireless systems to provision multimedia data services at appropriate QoS. In this paper, the authors propose a novel cross-layer joint priority (CLJP) packet scheduling scheme for QoS provisioning of multimedia traffic in satellite broadcast/multicast systems. The scheme considers both the application and transport layers' QoS requirements and RLC layer's queuing status into MAC layer packet scheduling decisions, aiming at guaranteeing diverse QoS demands and achieving efficient resource allocation subject to power/resource constraints. In comparison with existing schemes, the simulation results prove that the proposed scheme achieves better QoS and fairness, and enhances the throughput/channel utilisation. © 2007 by the American Institute of Aeronautics and Astronautics, Inc.
