Efficient Call Admission Control for MPEG-4 Wireless Videoconference Traffic

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 this work we propose a new efficient CAC scheme for MPEG-4 videoconference 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 videoconference traffic.
