Abstract

Packet and flow scheduling algorithms for WiMAX has been a topic of interest for a long time since the very inception of WiMAX networks. WiMAX offers advantages particularly in terms of Quality of service it offers over a longer range at the MAC level. In our paper, we propose a scheduling scheme that is compatible with 802.16 MAC protocol and can efficiently serve real time bursty traffic with reduced latency and hence improved QOS for real time flows. Simulation results show reduced latency, improved bandwidth utilization and throughput for real time bursty flows compared to the DRR scheme in similar traffic conditions.
