Vehicle To Vehicle Communication Using LiFi Technology

International Journal of Advanced Research in Science, Communication and Technology, 2022
The goal of the project is to reduce the consequences of accidents in our daily lives and to prevent automobile collisions. There are a variety of reasons for such a bad situation that leads to death or disability. This involves a driver’s rapid lack of concentration, braking failure, and loss of stability. Li-Fi is an advanced technology. This project
