Abstract
The deployment of WLAN-based solutions for efficient distribution of multimedia content over wireless links is rapidly increasing in the last few years. Nevertheless many performance issues concerning the delivery of high bit rate stream- oriented content using current IEEE 802.11 standards and the measurements of the customers satisfactions in terms of perceived quality, are still open and of great interest. This paper proposes a simple curve fitting technique for estimating, in a fast and accurate way, the perceived quality of streaming media contents delivered within a wireless network. The model accounts for the effects of various network parameters such as congestion, radio link power and video transmission bit rate. The correctness of the designed model has been verified through many different measurements in realistic wireless environments through an ad-hoc test bed.
