Abstract
The advent of cognitive radio (CR) technology in intelligent transportation system (ITS) paved the way for new advancements in vehicular ad hoc network (VANET) communication. The prompt sensing of spectrum is an important issue in CR-VANET minimizing the interference to primary user (PU). In real time, less time means small data. The employment of cooperative sensing along with clustering in CR-VANET mitigates this problem. In this chapter, a clustering scheme using limited data sets is used. Due to the dynamic topology of VANET, a clustering algorithm is used considering node degree, speed and location. The simulation results show that the proposed clustering detects the PU signal in a relatively low SNR condition compared to single-user spectrum sensing.
