  • A method (VP-PRMA) based on the users demand to improve the performance of voice service in PRMA system is proposed. In the paper, a new system measurement based on relative penalty factor is used. After the analysis of PRMA, the new method, using variable contend probability according to the actual condition, is presented. According to the simulation, the proposed method improves the voice performance as expectated.
