A flexible MAC protocol for the integration of high- and low-quality video streams, voice and data traffic over high-speed packet switched wireless networksA flexible MAC protocol for the integration of high- and low-quality video streams, voice and data traffic over high-speed packet switched wireless networks Peer-Reviewed Journal Publication Δημοσίευση σε Περιοδικό με Κριτές 2015-10-252006enIn this work, we propose and evaluate mechanisms for the multiplexing and the integrated delivery of various traffic types such as video, data and voice, over a wireless cellular high-speed packet switched network. Two different scenarios are examined where the video traffic results from videoconference sessions and high-quality media playback, respectively. In both cases we focus on the uplink channel and we thoroughly investigate, by using actual MPEG-4 video streams, the system's performance under a variety of possible loads. Our goal is to achieve high-aggregate channel throughput while preserving the quality of service requirements of each traffic type.Δημοσίευση σε επιστημονικό περιοδικό http://creativecommons.org/licenses/by/4.0/AE� - International Journal of Electronics and Communications / Archiv f�r Elektronik und �bertragungstechnik460306–315 Spyros Psychis Ψυχης Σπυρος Koutsakis Polychronis Κουτσακης Πολυχρονης Paterakis Michalis Πατερακης Μιχαλης Elsevier Wireless packet switched networks Medium access control protocols Integrated traffic access MPEG-4 streams
