Light Fidelity (Li-Fi) for Vehicular Communication: A Comprehensive Study

Abstract

When taking on-the-road journey, people are at risk as accident may occur anytime. Committing small mistakes when driving in high traffic areas may lead to fatality. A combination of traffic signals and signboards has been put in place to assist the public in avoiding similar incidents. Nonetheless, accidents continue to occur as a result of people’s ignorance. Therefore, it is essential to develop approaches that can inform drivers in a certain way, particularly in the vehicle
environment. This study examined the acceptance of Light Fidelity, known as Li-Fi, as an alternative means of data
communication between vehicles. The tool has been developed following an embedded system design approach that
incorporates both hardware and software components. The information source was transmitted and received using
photodiodes and integrated LEDs. The tool was tested in an experimental setup of two scenarios that warn potential vehicles of different contexts, such as sudden braking and road work ahead. Although the study proves the concept, further testing is required as actual implementation may vary and related factors need to be considered. The study contributes to the conceptual idea of how Li-Fi is incorporated into vehicles and could be a solution for inter-vehicle communication.
