ABSTRACT
This chapter tackles the challenging task of performance evaluation and dimensioning of WiMAX networks. It provides a simple analytical model which is able to take into account the effects of elastic traffic, radio channel variations, and scheduling policy. Compared to packet-level simulationbased evaluations, ourmodel instantaneously delivers the dimensioning parameters necessary for the deployment of aWiMAXnetwork. Compared to existing analytical solutions, we derive closed-form expressions for all performance metrics. We compare the results obtained through analytical model with those of simulations.We show that our analyticalmodel is not only accurate but also robust with respect to the modeling assumptions. Finally, the quick results produced through our analytical tool allow to carry out dimensioning analyses that otherwise require several thousands of evaluations, which would not be tractable with any simulation tool.
