On Multiple Traffic Type Integration over Wireless TDMA Channels with Adjustable Request Bandwidth

摘要

A new medium access control (MAC) protocol for mobile wireless comunications is presented and investigated. We explore, via an extensive simualtion study, the performance of the protocol when integrating voice, video and data packet traffic overa a wireless channel of high capacity (referring to an indoor microcellular environment). Depending on the number of video users admitted into the system, our protocol vaires: a) the request bandwidth dedicated to resolving the voice users contention, and b) the probability with which the base station grants information slots to voice users, in order to preserve full priority for video traffic.
