This paper proposes a fair and efficient QoS scheduling scheme for IEEE802.16 BWA systems that satisfies both throughput and delay guarantee tovarious real and non-real time applications. The proposed QoS scheduling schemeis compared with an existing QoS scheduling scheme proposed in literature inrecent past. Simulation results show that the proposed scheduling scheme canprovide a tight QoS guarantee in terms of delay, delay violation rate andthroughput for all types of traffic as defined in the WiMAX standard, therebymaintaining the fairness and helps to eliminate starvation of lower priorityclass services. Bandwidth utilization of the system and fairness index of theresources are also encountered to validate the QoS provided by our proposedscheduling scheme.
