Spectrum sensing challenges & their solutions in cognitive radio based vehicular networks

Vehicular ad hoc network (VANET) has been established to mitigate road collisions and traffic congestion and provide infotainment facilities to users. Allocated channels to VANET, which is the DSRC (Dedicated Short-Range Communication), are not adequate for the full implementation of VANET. Cognitiv...
