Fair Connection Admission Control Scheme for IEEE 802.16e Systems

The IEEE 802.16e standard provides Quality of Service (QoS) guarantees for users based on the conception of connection-oriented service. However, fairness has not been considered in existing connection admission control solutions, which is very important for user experience. In this paper, we propose a fair connection admission control scheme (FCAC) to improve the system´s fairness on bandwidth allocation to users by setting a dynamic admitting threshold. FCAC considers a common scenario that users are limited to the fixed amount of bandwidth by Internet Service Provider (ISP). Simulation results show that FCAC can improve service fairness for users without degrading the performance of the system.
