Abstract

The design of efficient packet scheduling algorithms is crucial to the radio resource management (RRM) in the satellite digital multimedia broadcasting (SDMB) system, which has emerged as a promising solution to the multimedia content delivery. In order to achieve more efficient quality of service (QoS) provisioning among different multimedia services, a novel packet scheduling algorithm, namely combined delay and rate differentiation (CDRD) packet scheduling, is proposed in this paper. This algorithm takes into account key QoS parameters aiming at fairly prioritising and scheduling heterogeneous multimedia contents in satellite environment. Its performance has been evaluated via simulations. The results show that, in comparison with existing scheduling algorithms, CDRD achieves better performance on delay, jitter and channel utilisation.
