The most important protocol used is WAVE (Wireless Access in Vehicular Environment) to provide spectrum for\nvehicular communication. I have analyzed that WAVE is not able to allocate required spectrum for efficient exchange of\nsafety related information. In other words, Delay in message transmission and Loss of data packet is not acceptable and\nincreases the requirement of the system. In this paper, I have reviewed a current work [1] which provides guarantees to the\ndelivery of data using Cognitive Radio technology in high density Vehicular ad hoc network. The main goal of that work is\nto generate safety packets and transmitted during the same period of time. This system continuously monitors the delay\nveteran by the vehicles on CCH where all the safety related information ought to be transmitted. In any case, if the delay\nexperienced by the vehicles is more than the threshold value, the system needs to extend the bandwidth of the channel using\ncognitive Radio networks. The RSU (Road Side Unit) contains feedback control design in which extra bandwidth is included\nto drive the delay that is below the threshold value. I have reviewed theAnalysis of various parameters such as Delay, Packet\nDelivery Ratio, Throughput and Loss which give the guarantees of data delivery in VANET and increases safety on the road.
