Abstract
This paper proposes a novel simulation framework designed to assess the performance of wireless cognitive networks in realistic scenarios. The simulation framework is based on the combination of the OMNeT++ discrete event simulator with Matlab functionalities. The popular INET simulation package for OMNeT++ is extended with the introduction of cognitive functionalities and integrated with a more accurate wireless channel model developed in Matlab, which is employed to simulate propagation e ects of any radio activity and serves as an input for spectrum sensing algorithms. The utilization of a general purpose network simulator makes it possible to evaluate the algorithm's efficiency from a system-level point of view; moreover, it allows us to take into account many factors which in uence network behavior in real scenarios (for example, node mobility), that would usually be neglected in analytical analyses.
