Dynamic Reservation TDMA Protocol for Wireless ATM Networks Jean-Fran

A Dynamic Reservation TDMA Multiple Access Control (DR-TDMA) protocol that extends the capabilities of Asynchronous Transfer Mode (ATM) networks over the wireless channel is proposed in this paper. DR-TDMA combines the advantages of distributed access and centralized control for transporting Constant Bit Rate (CBR), Variable Bit Rate (VBR) and Available Bit Rate (ABR) tra c e ciently over a wireless channel. The contention slots access for reservation requests is governed by the Framed Pseudo-Bayesian Priority (FPBP) Aloha protocol that provides di erent access priorities to the control packets in order to improve the Quality-of-Service (QoS) o ered to time sensitive connections. DR-TDMA also features a novel integrated resource allocation algorithm that e ciently schedules terminals' reserved access to the wireless ATM channel by considering their requested bandwidth and QoS. Integration of CBR, voice, VBR, data and control tra c over the wireless ATM channel using the proposed DR-TDMA protocol is considered in the paper. Simulations results are presented to show that the protocol respects the required QoS of each tra c category while providing a highly e cient utilization of approximately 96% for the wireless ATM channel.
