Censoring has been proposed to be utilized in wireless distributed detection\nnetworks with a fusion center to enhance network performance in terms of error\nprobability in addition to the well-established energy saving gains. In this\npaper, we further examine the employment of censoring in infrastructure-less\ncognitive radio networks, where nodes employ binary consensus algorithms to\ntake global decisions regarding a binary hypothesis test without a fusion\ncenter to coordinate such a process. We show analytically - and verify by\nsimulations - that censoring enhances the performance of such networks in terms\nof error probability and convergence times. Our protocol shows performance\ngains up to 46.6% in terms of average error probability over its conventional\ncounterpart, in addition to performance gains of about 48.7% in terms of\naverage energy expenditure and savings up to 50% in incurred transmission\noverhead.\n
