This paper proposes an analytical model to predict the quality of video, expressed in terms of mean square error of the received video frames, in an IEEE 802.11e wireless network. The proposed model takes into account contention at the MAC layer, wireless channel error, queueing at the MAC layer, parameters of different 802.11e Access Categories (AC), and video characteristics of different H.264 data partitions. To the best of the authors' knowledge, this is the first model that takes these network and video characteristics into consideration to predict video quality in an IEEE 802.11e network.
