Optimization of Number of Secondary Users in CSS for Maximizing the Spectrum Utilization
Deepika Rajpoot, Pankaj Verma · 2020
Cognitive Radio (CR) networks offer the solution to the problem of spectrum deficiency by increasing the use of the spectrum. In CR networks, Cooperative Spectrum Sensing (CSS) aids to improve the sensing performance by utilizing spatial diversity and enhances the spectrum access possibilities for Secondary Users (SUs) or unlicensed users. With the help of this CR and CSS, the aim is to enhance the utilization of the available spectrum. In this paper, a mathematical model has been developed for optimizing the number of SUs to participate in the CSS to maximize the spectrum utilization.
