Enhancement Cooperative Spectrum Sensing In Cognative Radio Network

To combat spectral congestion, cognitive radio employs opportunistic utilization of the frequency ranges that are rarely used by authorized users. Because of the placements of the devices, the primary transmitter's signal may not be identified, spectrum sensing is crucial in cognitive radio to prevent collisions with licensed users and to increase the effectiveness of allowed spectrum use (hidden primary user problem). The proposed system simulates the file and picture file data types in the cognitive radio network environment. The simulation program OMNET++ was also used to design the suggested system. As compared to the situation without FC, the suggested hybrid sensing system of the Fusion Center (FC) increased throughput by 135.026% for 2 nodes, 75.2% for 4 nodes, 34.26667% for 6 nodes, and 30.6% for 8 nodes. In the situations of 2 CR, 4 CR, 6 CR, and 8 CR, respectively, the power consumed was decreased for better results by 25.3104%, 8.370582%, 3.329049%, and 1.989248%. Higher outcomes have CR life time increases of 74.68961%, 91.62942%, 95.75109, and 98.01075%. According to the situations of 2 CR nodes, 4 CR, 6 CR, and 8 CR.
