Abstract :
In recent years, Cognitive Radio (CR) has been regarded as the most promising technique for solving the problem of spectrum utilization. CR can scan the spectrum band and identify free channels which will be used by cognitive users with no harm to primary users. Due to the various dynamic characteristics of Cognitive Radio Networks (CRN), adaptation and secure communication are of greater significance than other wireless networks. In this paper, we propose an adaptive trust management mechanism based on cognition cycle, which can mitigate system error rate effectively and make spectrum allocation more reasonable and secure. Finally, simulation results show that the scheme has the advantages of strong adaptation and low error rate.
