On achieving accurate call admission control for videoconference traffic transmission over wireless cellular networksOn achieving accurate call admission control for videoconference traffic transmission over wireless cellular networks Πλήρης Δημοσίευση σε Συνέδριο Conference Full Paper 2015-11-102007enUser 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.http://creativecommons.org/licenses/by/4.0/3221 - 3226 IEEE Wireless Communications and Networking Conference Koutsakis Polychronis Κουτσακης Πολυχρονης Paterakis Michalis Πατερακης Μιχαλης Chatziperis ,S Institute of Electrical and Electronics Engineers Communication systems, Wireless Wireless data communication systems Wireless information networks Wireless telecommunication systems wireless communication systems communication systems wireless wireless data communication systems wireless information networks wireless telecommunication systems
