Abstract
In this paper, we propose an adaptive Call Admission Control for IEEE 802.16 scheduled flows. As the WiMAX defined services aim to adapt the bandwidth grant to the data rate of accepted sessions, a powerful CAC that takes into account flows characteristics and their heterogeneities must be used. Our proposal aims to take advantage of the variability of traffics and to adapt the CAC according to the characteristics of incoming flows. We apply this adaptive CAC to the case of video traffics using measurements done by the BS to guess and classify flows according to the similarities in their behaviours and then adapt the system model parameters that will be used by the CAC. In this purpose we use a Markovian model adapted for each flow instead of a generic one. Performance evaluation is given to demonstrate the interest of our proposal.
