Abstract
This paper proposes a traffic modeling and a simulation methodology to assist the dimensioning of the capacity of advanced wireless systems. Knowingly, such systems accommodate a diversity of services with corresponding different bandwidth and traffic characteristics, which leads to intricate dimensioning solutions. In our methodology, we treat each type of traffic using its proper model and bundle them in a simulation tool. A fundamental contribution of this work is the proposal of a simulation tool that incorporates general traffic models to yield the performance of the various traffic flows requiring different bandwidths when sharing the same pool of resources in a loss system consisting of a link with a limited capacity. Given the generality and complexity of the model, analytical solutions are not available, and simulation has proven to be a beneficial tool for analyzing and dimensioning the system, with surprising results.
