Design and implementation of a vehicle to vehicle communication system using Li-Fi technology

In this paper, we present initial designs and results of a small-scale prototype of a vehicle to vehicle communication system using light fidelity (Li-Fi) technology, a new technology that was developed in the last few years, which still needs more investigations on its sustainability for outdoor vehicular networks. Vehicle to vehicle communication is the most effective solution that has been used in order to reduce vehicles´ accidents. The proposed use of Li-Fi technology in this paper comprises mainly light-emitting diode (LED) bulbs as means of connectivity by sending data through light spectrum as an optical wireless medium for signal propagation. In fact, the usage of LED eliminates the need of complex wireless networks and protocols. Several case studies mimicking the vehicle to vehicle communication are explored in this work. Both numerical simulations using Proteous package and experimental results are also presented, which agree quite well.
