Dynamic reservation TDMA protocol for wireless ATM networks

A dynamic reservation time division multiple access (DR-TDMA) control proto col that extends the capabilities of asynchronous transfer mode (ATM) netwo rks over the wireless channel is proposed in this paper DR-TDMA combines th e advantages of distributed access and centralized 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 acce ss for reservation requests is governed by the framed pseudo-Bayesian prior ity (FPBP) Aloha protocol that provides different access priorities to the control packets in order to improve the quality-of-service (QoS) offered to time sensitive connections. DR-TDMA also features a novel integrated resou rce allocation algorithm that efficiently schedules terminals' reserved acc ess to the wireless ATM channel by considering their requested bandwidth an d QoS, Integration of CBR, voice, VER, data, and control traffic over the w ireless ATM channel using the proposed DR-TDMA protocol is considered in th is paper. Simulation results are presented to show that the protocol respec ts the required QoS of each traffic category while providing a highly effic ient utilization of approximately 96% for the wireless ATM channel.
