Base station MAC with APRMA protocol for broadband multimedia ATM in micro/pico-cellular mobile networks

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.

-The future broadband wireless asynchronous transfer mode (ATM) networks must provide seamless extension of multimedia services from the wireline ATM networks. This requires an efficient wireless access protocol to fulfill varying Quality-of-Service (QoS) requirements for multimedia applications. In this paper, we propose a multiple access protocol using centralized and distributed channel access control techniques to provide QoS guarantees for multimedia services by taking advantage of the characteristics of different kinds of ATM traffics. Multimedia traffic, including constant bit rate (CBR), variable bit rate (VBR) and available bit rate (ABR) with different kinds of applications, such as voice, video-conferencing, MPEG video and Web-browsing, is considered to evaluate the proposed protocol. Simulation results show that the proposed multiple access protocol can support a wide range of telecommunication applications at the same time with high efficiency and guaranteed QoS.
