Abstract

The recent interest in tackling the frequency-dependent aspects of communications is pushing a demand for spectrum awareness in simulation tools. Unfortunately, most current network simulators do not deal with this aspect in a satisfactory fashion. In this paper, we present a framework that we developed for the ns3 simulator with the aim of addressing this issue. We discuss the modeling assumptions on which our design is based, and we describe in detail the implementation of the framework as well as of the PHY layer modules that we developed on top of it. Finally, we report some performance evaluation results which show that the proposed solution can achieve a good spectrum modeling accuracy with a modest increase in the computational load.
