Abstract:

This project develops an automatic vehicular communication system using Li-Fi technology, which provides improved efficiency by enabling vehicles to communicate by sending and receiving commands or help related messages with each other. Inter-vehicle communication is an effective method in which the communication takes place within the vehicles by which transmit various messages such as ignition on/off, sunroof on/off, wiper on/off, directions of the car, oil leakage, door open, need for some help. In Li-Fi technology, for communication in the vehicle, data is transmitted using an LED bulb or Laser, and at receiving end, we use a photodetector like a solar panel to receive the data. The usage of a Laser beam instead of complex wireless and as well as wired networks. Li-Fi (Light Fidelity) is an emerging technology that uses the visible light spectrum for communication. This project focuses on the automatic operation of a car, safety on roads in which consists of Li-Fi acting as a transmitter communicate with a photosensor or solar panel acting as a receiver. The application is cost-effective as Laser are cheap and simple algorithms are proposed for audio signal generation, processing, transmission, and visualization. The basic transceiver and receiver circuits are implemented, and the results are connected through Arduino to the system by using LabVIEW to visualize the audio signal or operation part of the car. The car moves in corresponding to the commands, and this helps to make the driving easy.

Keywords:
