Performance evaluation of MPEG-4 video over realistic EDGE wireless networks

This paper examines the performance of the delivery of MPEG-4 video over a realistically emulated EDGE (Enhanced Data for GSM Evolution) wireless network. The video delivery system is based on MPEG-4 video simple profile and on the IETF protocols RTSP, RTP, and RTCP for the media delivery and synchronization in compliance with the 3GPP specifications for packet streaming services (PSS). The EDGE network emulator is based on a well-verified Markov chain model. The effect of the different EDGE network parameters is evaluated in terms of video quality.
