Title
Bandwidth and Delay Guaranteed Call Admission Control Scheme for QOS Provisioning in IEEE 802.16e Mobile WiMAX
Abstract
An efficient Call Admission Control (CAC) scheme for IEEE 802.16e Mobile WiMAX that satisfies both bandwidth and delay guarantee to the admitted connections has been proposed in this paper. The proposed CAC scheme provides higher priority to Handoff connections, because it is more annoying to drop an ongoing connection than blocking a newly originated connection. Also UGS connections are given higher priority because UGS is the most common service used by the people for communication in everyday life. An analytical model is developed to evaluate the performance of the CAC scheme. The proposed CAC scheme is compared with two other existing CAC schemes proposed in literatures. Numerical results show that the proposed CAC scheme could be the better choice forAn efficient Call Admission Control (CAC) scheme for IEEE 802.16e Mobile WiMAX that satisfies both bandwidth and delay guarantAn efficient call admission control (CAC) scheme for IEEE 802.16e Mobile WiMAX that satisfies both bandwidth and delay guarantee to the admitted connections has been proposed in this paper.

An analytical model is developed to evaluate the performance of the CAC scheme. The proposed CAC scheme is compared with two other existing CAC schemes proposed in literatures. Numerical results show that the proposed CAC scheme could be the better choice for admission control in terms of blocking and dropping probabilities of the connections and bandwidth utilization of the system.
