Executive Summary

This paper presents a simple and accurate analytical model for performance evaluation of WiMAX networks with multiple traffic pro les. This very promising access technology has been designed to support numerous kinds of applications having different traffic characteristics. The need for accurate and fast-computing tools is thus of primary importance to face complex dimensioning issues that integrate this traffic profile diversity. This product-form queueing model provides closed-form expressions giving all the required performance parameters for each traffic pro le at a click speed. The model is compared with extensive simulations that show its accuracy and robustness. Finally, the speed of the analytical tool allows to carry on a preliminary performance study.
