Abstract :
In this paper, we propose a layered access control protocol, which incorporates a dynamic polling scheme on a burst level into the fair cell scheduling (polling-based wireless access burst scheduling: P-WABS) algorithms. Both the real-time and non-real-time multimedia services can be efficiently supported under the framework of the layered access control in the wireless ATM networks. Since it provides a contention-free access control mechanism, it turns out to be adequate for the multimedia services with the real-time constraints. Multimedia service traffic, including the constant bit rate (CBR), real-time variable bit rate (rt-VBR) and available bit rate (ABR) services, is considered to analyze the proposed scheme. Simulation results show that the proposed approach significantly improves the cell loss performance of rt-VBR services while a reasonable level of fairness is achieved for the ABR services
