Abstract: Vehicle to vehicle data transmission, we present initial designs and results of a small-scale prototype using light fidelity (Li-Fi) technology, a new technology that was developed in the last few years, which still needs more systematic inquiry on its sustainability for outdoor vehicular networks. Vehicle to vehicle communication is the most effective solution we have used in order to reduce vehicle's accidents. In Li-Fi technology for vehicle-to-Vehicle data transmission we use LED bulb. In this technology there is elimination protocols use so in Li-Fi technology complexity get reduce. The aim of designing this system is highly reliable which give desired data transmission between vehicle-to-Vehicle by using transmitter and receiver mounted on vehical.
