Efficient Traffic Policing for Videoconference Traffic over Wireless Cellular Networks

The constant development of new multimedia applications which are "greedy" in terms of bandwidth and Quality of Service requirements calls for new approaches to the traffic policing problem. In recent work we have modeled the behavior of multiplexed H.263 videoconference traces. Our results lead us to introduce, in this work, a new video traffic model for single H.263 videoconference sources and to propose a new traffic policing scheme for wireless videoconference traffic, based on the model. To the best of our knowledge, this is the first work in the relevant literature where the token generator is based on a traffic model, and not on a fixed rate.
