IEEE 802.16 standard supports two different topologies: Point to multipoint (PMP) and mesh. In this paper, a QoS mechanism for point to multipoint of IEEE 802.16 and BS scheduler for PMP mode is proposed. This paper also describes quality of service over WiMAX networks. Average WiMAX delay, average WiMAX load and average WiMAX throughput at base station is analyzed and compared by applying different scheduler at base station and at fixed nodes.
Key words: QoS, PMP mode, WiMAX networks, wireless networks.
