| Summary: | An Adaptive Reservation Time Division Multiple Access (AR-TDMA) control protocol for Wireless Asynchronous
Transfer Mode (WATM) networks is proposed in this paper. AR-TDMA combines the advantages of distributed
access and centralised control for transporting Constant Bit Rate (CBR), Variable Bit Rate (VBR) and Available Bit
Rate (ABR) traffic efficiently over a wireless channel. The contention slots access for reservation requests is
governed by two protocols, the Adaptive Framed Pseudo-Bayesian Aloha with Adaptive Slot Assignment (AFPBAASA)
protocol and the Framed Pseudo-Bayesian Aloha with Adaptively Prioritised Controlled Capture (FPBAAPCC)
protocol. Both protocols provide different access priorities to the control packets in order to improve the
Quality-of-Service (QoS) offered to time sensitive connections. AR-TDMA also features a novel integrated resource
allocation algorithm that efficiently schedules terminals’ reserved access to the wireless ATM channel by
considering their requested bandwidth and QoS. Integration of CBR, voice, VBR, data and control traffic over the
wireless ATM channel using the proposed AR-TDMA protocol is considered in the paper. The performance of the
AR-TDMA in conjunction with the AFPBA-ASA protocol and FPBA-APCC protocol has been investigated and the
simulation results are presented showing that the protocol satisfies the required QoS of each traffic category while
providing a highly efficient utilisation of approximately 96% for the wireless ATM channel. |
