WiMAX (Worldwide Interoperability for Microwave Access) networks are the networks which are responsible for providing many services like video, data and voice. The WiMAX technology satisfies the modern need of broadband internet through wireless access. For managing all these services through WiMAX, IEEE802.16 gives QoS (Quality of Service) parameter. In WiMAX, a fundamental challenge is to achieve high QOS so that various parameters like waiting time, end to end delay can be minimized and other parameter like execution time and network utilization etc.
