Abstract: In this paper, we give a quantitative evaluation on the effect of integrating WiMAX and Wi-Fi, as compared to the case of separate WiMAX and Wi-Fi systems, with respect to the system capacity under QoS constraint. We focus particularly on the VoIP traffic aspects of the system. Based on this capacity evaluation, a cost analysis is further presented. We also propose and analyse a resource management scheme on Wi-Fi to WiMAX handover.

Keywords: integrated WiMAX/Wi-Fi access system; VoIP; capacity analysis; equivalent random traffic model; admission control; loss probability; handover; QoS; resource reservation; WiMAX; Wi-Fi; quality of service; resource management; wireless LANs; wireless networks.
