Abstract: Scheduling and call admission control (CAC) in IEEE 802.16 system play a vital role in the performance of the system. The 802.16 standard does not specify any scheduling architecture or CAC. Many proposals assume a bandwidth based CAC which only provides bandwidth guarantee, but cannot fulfill delay and jitter requirements. In this paper, we propose a CAC that ensures QoS guarantee in terms of bandwidth, delay and jitter. We also present a novel method of estimating bandwidth requirement of variable bit rate application to increase the resource utilization of the system. We present our simulation result to show the effectiveness of bandwidth estimation and better performance over bandwidth based CAC.
