Performance study of multi-traffic access in WiMAX

The performance of WiMax in a multi-traffic scenario is studied, including system throughput, access delay and packet dropping rate. The effects of frame structure, minimum contention window size and delay constraint on the performance are investigated for different prioritized applications. Simulation results show that, increased system throughput, reduced access delay and lower packet dropping rate can be achieved by selecting the optimum frame structure and accessing parameters for applications with different quality of service (QoS) requirements.
