Abstract :
IEEE 802.16 wireless MAN is expected to revolutionize of the broadband wireless access technology. The grant/request mechanism in IEEE 802.16 MAC provides different quality of service (QoS) for different service flows. In the paper, we discuss the QoS issue in IEEE 802.16 wireless MANs and propose an admission control scheme for services defined in the 802.16 specifications. Our proposed scheme provides the highest priority for UGS flows and maximizes the bandwidth utilization by bandwidth borrowing and degradation. We also develop an analytical model to evaluate the system performance. Some numerical results are included to provide a better understanding of our scheme.
