Collision Avoidance between Vehicles through LiFi based Communication System

Large numbers of road accidents are taking place all over the world due to the collision between vehicles. More than 1.2 million peoples died in road accidents in 2018, according to world health organization (WHO). Human safety is very important. The project idea is proposed to reduce the consequences of accidents in our daily lives and avoid collision between vehicles. There are various reasons for such adverse condition that results in death or disabilities. This includes sudden loss of driver's concentration, brake fails, loss of stability. These hazardous conditions can be overcome if there is communication protocol used in all vehicles and depending on their position drivers control the vehicles to avoid accidents. There are various vehicular communication system prototypes are available i.e., 5.9 GHz Dedicated Short Range Communication and Vehicular Ad-Hoc network. These radio frequency (RF) based communication system has some limitations i.e., interference, congested spectrum and security. These limitations can be overcome by using Visible Light Communication (VLC). It provides high bandwidth, security, interference immunity, and high data rate. VLC is a data communication system which uses visible light for high data transmission and reception. This technology is known as Light Fidelity (LiFi). This paper presents the novel method to avoid collision between two vehicles i.e. front and rear vehicles. The proposed LiFi based Vehicular to Vehicular (V2V) communication system is a cost effective solution with high data rate capabilities.
