In the VANET scenario the problem of collision between the mobile vehicles occurred, which is the main problem in VANET to remove of delay in safety message transmission the cognitive radio, can be utilized in transmission of safety messages. The cognitive network uses primary and secondary users on the basis of spectrum sensing is done to detect which spectrum is free at that time. Different approaches are used for safety transmission of message. These different approaches include Mac layer, which is used for error detection and transmission.
