PERFORMANCE EVALUATION OF A VOICE DATA INTEGRATED FAST PRMA PROTOCOL/

In this work. the performance evaluation of a voice and data integrate d fast PRMA has been done. In this newly proposed protocol, every data terminal has an infinite buffer and voice terminals can work independ ently of data terminals. Thus voice terminals have the higher priority over data terminals. We can. therefore, analyze voice and data subsys tems separately. For voice analysis, we use a Markov analysis. and we use the EPA method for data analysis in order to create an analytic fo rm. As performance measures. the voice packet dropping probability the average voice and data delays, and the total throughput have been der ived. It is shown how many voice and data terminals the fast PRMA prot ocol can accommodate in a frame under the constraints that the voice p acket dropping probability should be less than 0.01, and average data packet delay should be less than 250 msec. We also discuss the stable region ibr this system. Numerical results show close agreement between analysis and computer simulation.
