Vehicle to Vehicle Communication Using Li-Fi

Communication between vehicles, also called vehicle-to-vehicle communication, is essential for traffic safety, traffic management, and smart transport systems. Although radio frequency (RF) and dedicated short range communication (DSRC) have made significant progress in V2V communication, existing wireless technologies also experience problems with spectrum, interference, and low data rate. We know that the increasing number of vehicles in the road has led to congestion and accidents. A key challenge is that there is a lack of real time communication between vehicles, which can prevent accidents and improve traffic flow to address this issue, we propose a vehicle to vehicle (V2V) communication system using Li-Fi (Light Fidelity) technology. Li-Fi offers high speed, secure, and interference free communication by simply utilizing the visible light for data transmission. The proposed solution is feasible due to the wide usage of LED headlights and taillights in vehicles, which can serve as transmitters and receivers for Li- Fi signals. This paper investigates about Light Fidelity (Li-Fi), as a substitute communication system in V2V communication. It uses Li-Fi transmitters and receivers embedded in the automotive lighting system that enables real-time exchanging data, traffic management, and coordinating autonomous vehicles. The paper evaluates the performance of the proposed system over various conditions including data rate and latency. The results provide insight into Li-Fi performance in comparison to existing wired and wireless technologies. Finally, this paper discusses some of the limitations, such as line of sight dependency and environmental effect, and proposes possible future research directions and better Li-Fi protocols.
