Implementation of Li-Fi based Multi-hop Ad Hoc Network for Inter Vehicle Communication

Avoiding accidents and traffic congestion use major concerns of the country. Various articles and studies have shown that these accidents could have been avoided if the driver was prescient about the approaching vehicle or the maneuver the car ahead is about to take. Hence a need of communication between vehicles arises. This paper focuses on present techniques used for Inter-Vehicle Communication (IVC) as well as for Vehicle to Infrastructure (V2I) Communication, using Radio waves as a medium of message transmission. Overcoming the limitations of the present central sensor-based networks, a new multi-hop ad hoc network which uses light as a medium to transfer data at high speed. To validate the proposed Light fidelity (Li-Fi) system, an experimental setup was made using ATmega328 to transmit the data using Light Emitting Diode (LED). Light bulb and bit error rates were calculated at various disturbances between the transmitter and various intensities of the light source.
