Abstract
The future broadband wireless networks require an efficient access protocol to fulfill varying quality of service (QoS) requirements for multimedia applications. In this paper, the packet reservation multiple access (PRMA) protocol is adopted for the transmission of voice and data over the wireless channel, then the protocol is modified in order to support video traffic. The proposed protocol aims at satisfying the stringent requirements of video traffic as well as achieving better channel utilization. Two models of different traffic weights are considered to evaluate the performance of the proposed protocol. Simulation results show that, the protocol achieves high efficiency and guaranteed QoS.
