Abstract - We are striving to build a system that will transmit pre-accident information to the vehicle, allowing the vehicle to avoid an accident, in this project. The designs and findings of a basic prototype of a vehicle-to-vehicle communication system based on light fidelity (Li-Fi), a unique technology developed in recent years, were investigated. One of the most effective strategies for decreasing car accidents is vehicle-to-vehicle communication. The proposed application of Li-Fi technology in this project primarily uses light-emitting diode (LED) bulbs as a mode of connectivity, with data delivered over the light spectrum as an optical wireless channel for signal propagation. In consequence, LED lighting eliminates the requirement for a complicated wireless network protocol. Key Words: Ultrasonic Sensor, Arduino, Motor, LiFi Transmitter and Receiver. 1.INTRODUCTION Li-Fi is a widely used and vital communication technology. Li Fi stands for light fidelity communication systems. It is an incredibly fast and low-cost wireless communication system that is the optical equivalent of Wi-Fi. The method transmits digital data that is invisible to the naked eye using light emitting diodes (LEDs). We build a prototype for vehicle-tovehicle data transmission utilising Li-Fi technology in this project. The most efficient strategy of preventing automobile accidents has been demonstrated to be vehicle to vehicle communication. In LI-Fi technology, the LED is used as a light source for data transfer via light. Vehicle to vehicle communications, for example, is one of the earliest developments. It was formerly used to replace or update existing wireless technology. to quickly restore high-speed connectivity (in case of disaster problem). LiFi is employed because it is an optical version of Wi-Fi that is speedy and affordable. LiFi technology will allow us to connect to the internet using light from lamps, streetlights, or LED televisions. Not only is it less expensive, safer, and faster than wifi, but it also eliminates the need for a router. Simply point your phone or tablet at a light bulb to access the internet. LiFi (light fidelity) is a two-way wireless technology that transmits data using LED or infrared light. Unlike wifi, which utilises radio frequency to convey an internet signal, LiFi technology uses light waves to transmit an internet signal. © 2022, IRJET

This is a significant improvement over today's wireless networks. It increases the bandwidth and speed of wifi, 3G, and 4G connections. These have a finite capacity and become saturated as the number of users surfing grows, causing them to crash, slow down, or even disconnect. However, LiFi's band frequency of 200,000 GHz is 100 times faster than wifi's 5 GHz limit and can transmit significantly more data per second. When the best wifi could only manage 300 Mbit/s, a 2017 study by the University of Eindhoven used infrared light with a radius of 2.5 metres to reach a download rate of 42.8 Gbit/s. Harald Haas, a director professor at the University of Edinburgh's LiFi Research and Development Centre, invented the technology, which could be available in our homes in a few years. It is currently being tested with LED luminaires in offices around the world, and the aerospace industry is already looking for ways to incorporate it into aeroplanes. Other places where LiFi technology could become popular include airports, hospitals, and city streets. According to the Global Market for LiFi Technology Analysis and Forecast 2018-2028, the growth of mobile devices and the growing demand for greater bandwidth systems will drive the development of this social technology in the coming decade. According to this analysis, the global market will be worth almost $36 billion in 2028, with a compound annual growth rate of 71.2 percent over the next ten years. Up to 2028, the Asia-Pacific area will dominate global growth in LiFi technology, surpassing Europe, which held the lead in 2017.
2. RESEARCH AND DATA With the introduction of new technologies such as 3G and 4G, we are running out of radio spectrum capacity. In comparison, because light boxes are already existent and deployed, the VLC spectrum has greater spectrum space than the radio spectrum. Efficiency: There are 14 missing cellular radio base stations, each with a 5 percent efficiency. The cooling system has consumed the majority of the energy in the base station. Because LEDs require less energy, with that Li-Fi is very efficient. Radio waves can pass through walls, allowing them to be intercepted and exploited. Light waves do not pass through solid objects. As a result, they cannot be intercepted.
