Abstract: Cognitive Radio (CR) is the key enabling technology which is used to sense, measure, learn, and be aware of the parameters of the radio channel, availability of power and spectrum, modulation schemes, radio’s operating environment, available infrastructures and number of active users etc. In this paper, a simulation framework of CRN is proposed which is based on NetSim Version 9.0 simulator. This framework can be used to investigate and evaluate the impact of operational interval on the performance parameters such as spectral efficiency, delay, Interference time, and throughput of the CRN. CRNs performance parameters such as spectral efficiency, delay, interference time, and throughput are evaluated over Cognitive Radio Networks (CRNs) using NetSim. This work also demonstrates some important network parameters such as packet transmitted, payload transmitted, and overhead transmitted. Individual Link throughput and application throughput are also demonstrated by enabling the real-time trace in NetSim at different operational intervals. These network performance parameters play an important role in real-time reliable applications. Analysis of the results demonstrate that the throughput and spectral efficiency increases with increase in operational interval. It is also demonstrated that the delay is decreasing with increase in operational interval.
