Abstract

An efficient bandwidth allocation scheme is proposed for supporting integrated services in wireless ATM networks. These include CBR, VBR and ABR types of traffic. The proposed scheme is based on A-PRMA for carrying ATM traffic in a dynamic TDMA type access system. It allows mobile users to adjust the reserved bandwidth according to their current demands and the wireless channel status. Extensive simulation results show that the proposed scheme can provide QoS guarantees with low cell transfer delay, high channel utilization (more than 70%) and short buffer length requirements
