Abstract	The IEEE 802.16e broadband wireless access (BWA) system is developed to cater for the rapidly growing requirement for multimedia wireless services. Since the heterogeneous services provided by the system are connection-oriented, admission control and associated resource reservation (RR) mechanisms are needed to achieve desired quality of service (QoS). In this paper, we develop a dynamic bandwidth reservation admission control scheme for the IEEE 802.16e system. In the proposed scheme, we set some overall reserved resource as admission guard bandwidth, which is dynamically adjusted according to the bandwidth request of on-going real-time variable-bit rate (VBR) services in addition to guaranteeing the resource requirement of potential handoff services. We also propose an analytical traffic model to evaluate the scheme. The results prove that our scheme can satisfy the bandwidth request of real-time VBR services and improve the system bandwidth utilization efficiently while guaranteeing the QoS requirements of all services at the same time.
