The advent of broadband wireless networks, such as WiMAX, is paving the way for the widespread deployment of high-bandwidth video streaming services for mobile users. To provide acceptable end-to-end performance in such a network, it is important to monitor the Quality of Experience (QoE) of the user, since the inherent variability in the wireless channel can undermine the video quality significantly. This paper undertakes a simulation study to evaluate the user's QoE (using PSNR as the representative metric) when video is streamed from a source to a Mobile Station (MS) via a WiMAX Base Station (BS). The WiMAX Forum's ns-2 simulator is used to carry out all the simulations.
