N2 - IEEE 802.16 standard defines the broadband wireless access specification for WiMAX without any standardized schemes for resource allocation and scheduling, which has thus been attractive to researchers in the past few years. In this paper, a downlink resource allocation algorithm, named the Multi-Round Resource Allocation scheme, is proposed for OFDMA based PMP system in WiMAX networks based on multiple service classes. The algorithm allocates the wireless resource according to the channel states of each mobile station, the inherent priority of each service flow, the QoS requirements of the service flows, and the fairness among users as well as the fairness among the service flows. Simulation results show that the proposed algorithm has better performance in the average throughput, the average queuing delay, the loss rate and the fairness.
