ANALYSIS OF AN INTEGRATED VOICE AND DATA-TRANSMISSION SYSTEM USING PACKET RESERVATION MULTIPLE-ACCESS

Packet reservation multiple access (PRMA) is a channel access protocol proposed for the third generation wireless information networks which have attracted considerable attentions recently. By using the equilibrium point analysis (EPA), a PRMA integrated voice and data system has been studied in previous research. However, the error between numerical results of the analysis and those of simulation is relatively large, In this paper, we also study an integrated voice and data system with PRMA. The system performance is evaluated by using a Markov analysis method. First, some analytic models are constructed such that the system transition can be described by a Markov chain. Then, we calculate the entries of the one step state transition matrix using an iterative procedure. Finally, system performance measures, such as throughput and delay, are evaluated. Little error between numerical results of analysis and those of simulation indicates that the method is appropriate to analyze PRMA systems.
