Abstract
An analytical model of performance of a bandwidth allocation and admission control scheme in wireless mobile integrated services network is proposed. Due to the multimedia services and flexible QoS characteristics of the considered network, the proposed model includes two different classes of requests with priority, where each class allows different levels of QoS requirements. The proposed scheme considers an upgrade and degrade (u-d) mechanism, with the aim of keeping the requests at the highest possible level so as to give high quality whilst maintaining the performance of each class within the negotiated QoS. Instead of focusing only on the traditional metrics, we propose two important new metrics to evaluate the cost of the u-d mechanism and the QoS level provided. A comparison with other schemes in the literature concludes that our proposed scheme is mandatory if it is essential to respect the priority among classes and shows good performance from both user and service provider perspectives.
