Abstract

In the paper, we propose a media access framework for supporting integrated service including the real-time service, the controlled load service, and the best effort service in wireless networks. Three medium access mechanisms, the "Multi-classes fair scheduling", the "Single-class fair scheduling + DCF", and the "Single-class fair scheduling + DCF with threshold for controlled load service" are proposed in the paper to manage the traffic within a piconet. Moreover, a measurement based admission control algorithm is proposed to guarantee the QoS requirements for the requests. We compare the performance of the proposed access mechanisms by conducting simulations. The simulation results show that the "Multi-classes fair scheduling" mechanism is the best choice for the networks occupied by the real-time service; the "Single-class fair scheduling + DCF with threshold for controlled service" mechanism is the best for controlled service in general case.
