Automobile Collision Warning and Identification System using Visible Light and Wi-Fi Communication

This paper introduces a vehicle-to-vehicle (V2V) communication system based on visible light communication technology. A vehicle will transmit the data continuously to another vehicle in front of it using head light and the data is stored in the Secure Digital (SD) Card in comma separated value for future reference in case of emergency at the same time the data is stored in the cloud server for government reference for locate the most accident areas. Nowadays, people readily use internet in their day-to-day activities to accomplish their task by means of wireless or wired network. As users are increasing manifold, data transmission rate consequently decreasing. However, Wi-Fi imparts data rate of 150Mbps as per IEEE 802.11n, this speed is still not enough to suffice the needs of a user. Considering this, Visible light communication concept has been introduced. In this project, a comparative and analytic study about the speed of visible light and Wi-Fi communication is being done and also reduction of network jamming problem due to increasing users demand is also being done.
