E ect of Mobility on PRMA

PRMA, a packetized multiple access scheme for transmitting over short range radio channels, is a promising scheme to implement in a cellular system. PRMA requires little central control and allows handovers with minimal base station intervention. However when mobile voice terminals move from one cell to another, they forfeit the slots reserved for them and, in addition, encounter hand-oo delays. This leads to a degradation in voice quality. In this paper we use Equilibrium Point Analysis to analyze the eeect of terminal mobility on the performance of PRMA in a cellular environment. We derive expressions for PRMA's throughput and packet dropping probability, in the presence of terminal mobility. We employ a path enumeration technique based on Mason's gain formula for signal ow graphs to evaluate the packet dropping probability.
