An Efficient Spectrum Sensing Mechanism for CR-VANETs

VANET (Vehicular Adhoc Network), used for inter-vehicular communication nowadays is not sufficient due to increase in traffic day by day.Hence use of CR (Cognitive Radio) is being considered for vehicular communication. In this paper we propose an efficient spectrum sensing mechanism for sensing and sharing the CR spectrum by mobile vehicles, which combines best of Stand-alone sensing and Cooperative sensing techniques. The proposed mechanism not only improves the probability of correct detection but also diminishes the probability of misdetection.
