A Fair and Efficient Packet Scheduling Scheme for IEEE 802.16 Broadband Wireless Access Systems

This paper proposes a fair and efficient QoS scheduling scheme for IEEE 802.16 BWA systems thatsatisfies both throughput and delay guarantee to various real and non-real time applications. The proposedQoS scheduling scheme is compared with an existing QoS scheduling scheme proposed in literature inrecent past. Simulation results show that the proposed scheduling scheme can provide a tight QoSguarantee in terms of delay, delay violation rate and throughput for all types of traffic as defined in theWiMAX standard, thereby maintaining the fairness and helps to eliminate starvation of lower priorityclass services. Bandwidth utilization of the system and fairness index of the resources are alsoencountered to validate the QoS provided by our proposed scheduling scheme
