Call admission control and traffic policing mechanisms for the wireless transmission of layered videoconference traffic from MPEG-4 and H.263 video codersCall admission control and traffic policing mechanisms for the wireless transmission of layered videoconference traffic from MPEG-4 and H.263 video coders Πλήρης Δημοσίευση σε Συνέδριο Conference Full Paper 2015-11-092002enWe explore, via an extensive simulation study, the performance of call admission control (CAC) and traffic policing mechanisms proposed for transmitting multiple-layered videoconference movies over a wireless channel of high capacity, depending on the user's needs and requests. We focus both on MPEG-4 and H.263 coded movies, and, in the latter case, our scheme achieves high aggregate channel throughput, while preserving the very strict quality of service (QoS) requirements of the video traffic.http://creativecommons.org/licenses/by/4.0/2155 – 21593th IEEE International Symposium on Personal, Indoor and Mobile Radio Communications Koutsakis Polychronis Κουτσακης Πολυχρονης Paterakis Michalis Πατερακης Μιχαλης Psychis ,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
