Performance analysis of enhanced RAMA protocol for statistical multiplexing of speech in wireless PCS

Abstract

The Resource Auction Multiple Access(RAMA) protocol was proposed by N. Amitay for Fast resource allocations to mobile terminals. We have proposed an Enhanced RAMA (ERAMA) protocol yielding lower system delay and delay variations than does the RAMA protocol. In this paper. we model a two-stage queueing network to evaluate the performance of the proposed protocol in terms of mean access delay. mean buffering delay, talk spurt loss ratio. and channel utilization, under homogeneous voice connections. The analytical results yield upper estimates for the various performance indices, compared with those of the simulations.
