Abstract
IEEE 802.16 standard more commonly known as WiMAX is an upcoming standard popularized by WiMAX Forum. Quality of service in WiMAX is provided with help of five scheduling services with different properties. WiMAX standard does not define provisioning for providing bandwidth allocation to different scheduling services. Most algorithms focus on traffic classes having rigid time constraints and classes without real time requirements are neglected This paper proposes modified Weighted Fair Queuing Algorithm using concepts of fuzzy logic for grant of bandwidth to all types of traffic. It enables fair distribution of network resources to low priority traffic classes and helps to improve their performance. Simulations have been done for performance justification and results are encouraging.
