An Efficient Quality of Service Scheduling Strategy for IEEE 802.16 Broadband Wireless Access Systems

In this paper, an efficient QoS scheduling strategy is proposed for IEEE 802.16 BWA systems that satisfies both throughput and delay guarantee to the applications such as video and audio streaming, online gaming, video conferencing, Voice over IP (VoIP), File Transfer Protocol (FTP) and Web Browsing. The proposed QoS scheduling strategy is compared with an existing QoS scheduling scheme proposed in literature in recent past. Simulation results show that the proposed scheduling architecture can provide a tight QoS guarantee for all types of traffic as defined in the standard hence maintain fairness and helps to eliminate starvation of lower priority class services.
