Abstract	The IEEE 802.16 standard specifies the air interface of broadband wireless access (BWA) systems supporting multimedia services. The applications are varied in their nature and demand different performance levels in order to maintain the appropriate quality of service (QoS). The network should guarantee the pre-defined QoS requirements through an adequate resource allocation and admission control schemes. In this paper we propose a connection admission control method that takes into consideration specific QoS parameters of the ongoing connections and the new requests. The method is based on an optimization approach where the maximum allowed mean delay and the mean data queue lengths corresponding to the connections are used as decision criteria for accepting the new requests for service. The solution of the defined optimization problem also gives the optimal resource allocation. Since solving the optimization problem for a large number of connections can be time consuming, we propose a simple and practical algorithm for obtaining the optimal solution.
