Call admission control and traffic policing mechanisms for the wireless transmission of layered videoconference traffic from MPEG-4 and H.263 video coders
Polychronis Koutsakis, Michael Paterakis, Spyros Psychis · 2003
We 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.
