A Performance Analytical Model for MPEG-4 Video Quality over WLANs

An accurate model of IEEE 802.11e EDCA for video quality analysis is introduced in this paper. The analysis of the model considers not only the effects of collision loss from channel access competition but also wireless loss caused by interferences and fading. Using the model, we derive the video frame loss probability and distribution of access delay, and validate the accuracy of the proposed model through comparisons with other models via simulations based on video decoded frame rate.
