Abstract :
We describe an analytical model, based on a Markov chain, suitable to study different bandwidth allocation policies for video streams over a WiMax access link. The Markov chain models an MPEG source, wireless channel conditions derived from a model compliant with WiMax specifications, and different bandwidth allocation policies. Validation with simulation results shows the correctness of the analytical model. The model permits to discuss the properties of various bandwidth allocation policies in terms of wasted slots, amount of lost data and access delays.
