Abstract

The IEEE 802.16e standard provides five different scheduling services to meet the QoS requirement of multimedia applications and this paper investigates one specific scheduling service, i.e. rtPS scheduling. In order to relieve the serious MAC overhead problem in WiMAX system, an efficient scheduling algorithm for the rtPS services has been proposed in this paper. Also the algorithm has been implemented and evaluated in the WiMAX simulation platform developed based on NS-2. From the simulation results, we can see not only the QoS requirement is ensured, but the system performance is also optimized with reduced MAC overhead using the proposed scheduling algorithm.
