Inter-Vehicle Communication Using Li-Fi Technology

Abstract

Ensuring protection of travelers in speedy vehicles and other road-side commuters has always been the main emphasis of urban transportation authorities. Vehicle to Vehicle (V2V) communication is based on DSRC (Dedicated Short Range Communication). DSRCs are highly secure, short to medium range, high-speed wireless communication channels, which help vehicles to connect with each other for a shorter period of time. Through DSRC, two or more vehicles can exchange data regarding their speed, acceleration, distance and direction. Li-Fi (Light Fidelity technology) is defined as a light-based WiFi which uses light instead of radio waves to transmit information. In Li-Fi technology, for communication between two vehicle data is transmitted using bulb and at receiving end, photo detector to receive the data. In this technology none of vehicular protocol is used so it reduces the system complexity. Inter-vehicle communication is an effective method with productive results that the proposed system used in order to communicate between two vehicles and maintain safe distance between vehicles to prevent accidents. This can notify all vehicle drivers about things like lane change, approaching vehicle trajectory and relative speed of the other vehicle in real-time. Smart features of V2V will help vehicles to receive alerts on traffic congestion, obstacles, changing lanes on highways, traffic merging, railway crossing notifications, etc. So, the future of vehicular communication is Vehicle to everything (V2X) communication system, where vehicle communicates with any entity that may affect the vehicle including other vehicles, infrastructure, pedestrians, smart devices, other networks etc.
