Analysis of aggressive reservation multiple access schemes for wireless PCS

In this paper we examine the behavior of two access methods named Aggressive Resource Auction Multiple Access (ARAMA) and Aggressive Packet Reservation Multiple Access (APRMA) for packet oriented mobile networks providing voice and data services for short range communications. These methods use an aggressive approach whereby data users relinquish the resource to make room for voice users. Simulation results show that system capacity improves as more data terminals can be accommodated without causing any penalty on voice packet dropping and throughput. A comparison between the two access schemes where we provide voice packet dropping probability, distribution of data delay, statistical multiplexing gain, speech clipping statistics and system throughput is also reported.
