Resource Allocation and Game Theoretic Scheduling in IEEE 802.16 Fixed Broadband Wireless Access Systems

The IEEE 802.16 broadband wireless access (BWA) system offers a cost-effective solution to the last-mile wireless connection problem. To provide the necessary QoS guarantees to the multimedia traffic in BWA systems while utilizing the resources as efficiently as possible, optimal scheduling mechanisms and resource allocation strategies are needed. In this paper, we propose a dynamic resource allocation strategy considering the interference on the sub-carriers for the IEEE 802.16 fixed broadband wireless access (FBWA) system. We analyze the performance of the system using an M/G/l queuing model in terms of performance parameters such as average system throughput and packet loss ratio. We adopt a game theoretic approach to prioritize the traffic depending on the available bandwidth. Our analytical model is validated using simulations.
