Περίληψη

In this paper we explore, via an extensive simulation study, the performance of a new medium access control (MAC) protocol when integrating voice, video and e-mail data packet traffic over a wireless high capacity picocellular system, with errors. Depending on the number of video users admitted into the system, our protocol varies: 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. We evaluate the voice and video packet dropping probabilities for various voice and video load conditions, and the average email data message delays.
