Abstract

Visible Light Communication (VLC) by means of white Light Emitting Diode (LED) is an alternate and most promising technology for existing Radio Frequency (RF) communication. We proposed one of the important applications of VLC to prevent the theft of the vehicle. Every year approximately 36,000 vehicles worth Rs.115 crores are stolen in India. In critical road condition, only 15,000 are traced and many spare parts of vehicle are found missing. Even the existing technologies have some disadvantages related to the problem stated. In our paper, we dealt with the data communication through LED. One of the optical wireless communication having short range is called as VLC whose visible light spectrum starts from 380 nm and ends at 780 nm and it has an incomparable data rate of 10GB/s whereas the speed is 1MB/s on Bluetooth and for Infra Red (IR) the speed is 4MB/s. We try to achieve the communication through VLC between 1) car - car to prevent the accident and 2) car - tollgate and received signal from tollgate is transmitted to Global System for Mobile communication (GSM) network using microcontroller to prevent the theft of vehicle. To enhance the security of VLC, Advanced Encryption Standard (AES) algorithm is used and the result is illustrated with the help of LabVIEW.
