Vehicle Diagnostics and Vehicle to Infrastructure Communication through Visible Light Communication (VLC)

High Fidelity Communication has become a necessity in various sectors. Different wireless data transfer methods play a vital role in various far field and near-field communications. Wireless communication for transferring data through radio spectrum has been a continuous evolving trend, especially in Automotive Sector, with fleet monitoring, platooning and even connected vehicles. Some important parameters considered in selecting a wireless platform would be bandwidth, data transfer, speed and security. Some interesting advantages of communication over the visible spectrum has led to the evolution of Light Fidelity. Implementation of Visible Light Communication (VLC) in the automotive field might enable safer driving conditions through vehicle-to-vehicle (V2V) and vehicle to Infrastructure (V2I) communication with high data transmission rates and efficient-bandwidth usage. The principle of VLC is based on “line of sight” data transmission through modulation of the light source. Highly reliable vehicle-to-vehicle communication is possible with VLC through transmission and reception of data using visible light as the medium of communication. It also helps to reduce the downtime with on the fly diagnosis of the vehicle. In this paper, we propose a concept that uses VLC enabled vehicles and systems aimed at improved vehicle diagnostics, data handling and road safety. We shall also investigate possibilities of managing and reporting traffic violations accurately by means of deploying the VLC technology in real time applications. The paper also touches upon VLC in hybrid networks wherein it collaborates with the conventional networks to enable wireless communication across various scenarios and environments. Also, this paper would focus on the vehicle diagnostics through ECUs for faster data handling.
