User mobility, combined with the rapidly growing number of multimedia applications, form a challenging and yet unresolved problem for the development of call admission control schemes over next generation wireless cellular networks. In recent work the behavior of H.263 videoconference traces have been modeled with the use of a discrete autoregressive (DAR(Garawi et al., 2006)) model. Based on this model, a new efficient CAC scheme for videoconference traffic over cellular networks was proposed in this work, which uses precomputed traffic scenarios for its decision-making. The scheme is shown, via an extensive simulation study, to clearly excel in comparison with well-known existing approaches, in terms of quality of service (QoS) provisioning to users receiving videoconference traffic.
