Abstract :
In this paper, we investigate the behavior of multiplexed traffic streams of different traffic classes in the radio environment, and study the effect of such behavior on the performance of the on demand TDMA (D-TDMA) MAC protocol. An adaptive polling mechanism, referred to as polling respond-bandwidth reservation algorithm (PR-BRA), is proposed for providing a bounded channel access delay for the active/ready variable bit rate virtual channels (VBR VCs). The performance of PR-BRA is investigated under different traffic load and network conditions, and a general conclusion on the system performance is drawn
