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 we have modeled the behavior of H.264 video traces with the use of a discrete autoregressive (DAR(1)) model. Based on this model, we propose in this work a new efficient CAC scheme for H.264 video traffic over cellular networks, which uses precomputed traffic scenarios for its decision-making. Our 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 video traffic
