An escalation in interest of Worldwide Interoperability for Microwave Access (WIMAX) networks has been substantiated due to its high data rate, wide area coverage and differentiation of Quality of service. Adequate schedulers play a preeminent role in rendering these operational specifications. In this paper we abduce weighted round robin scheduling algorithm that not only fulfills the quality of service requirement but also provides a fair scheduling for real-time services. In this work, a comprehensive study was carried out of scheduling algorithms such as Weighted Round robin, round robin, strict priority and weighted fair queuing, analyzing and appraising the performance of schedulers individually in order to support the different QoS classes. The simulation is carried out via Qualnet 6.1 simulator and the results implied that Weighted Round Robin out performs other schedulers and provides higher service standard to support the different QoS requirement.

Keywords: IEEE 802.16 (WIMAX), QoS, Qualnet, Scheduling Algorithm.
