WiMAX (Worldwide interoperability for Microwave Access) is expected to arise as the main Broadband Wireless Access (BWA) technology providing voice, data and video services with different type of QoS (Quality of Service). Although different type of QoS classes had been defined by the IEEE 802.16 standard, the scheduling architecture is left to be vendor specific. Designing an efficient scheduling algorithm provide high throughput and minimum delay is challenging for system developers. In this paper, a detailed simulation study was carried out for some scheduling algorithms such as WFQ, round robin, WRR and strict-priority, analyzing and evaluating the performance of each scheduler to support the different QoS classes.
