Abstract:
In this paper, an adhoc Cognitive Radio Network (CRN) having multiple Primary Users(PU) and multiple Secondary Users (SU) is proposed. The spectrum sensing and allocation for the SUs are performed on the Universal Software Radio Peripheral (USRP) test bed. The real-time environment signals are considered for the proposed CRN performance analysis. The CRN’s participation of SUs in spectrum sensing and spectrum allocation has been analyzed using cooperative spectrum sharing and the Coalition Game Theoretic (CGT) approach. A CGT spectrum allocation technique for the proposed CRN with a primary and backup channel allocation scheme has been investigated. The result shows that the channel allocation scheme is realistic. It improves SUs participation in CRN functions. It gives high spectrum utilization efficiency and causes negligible interference to neighbouring SUs/PUs. The spectrum utilization is up to 92.85% for specific scenarios of SU coalitions.
