Secured and green data processing and transmission in a human-vehicle interaction ADAS system

Abstract

Using light waves instead of radio waves, the Visible Light Communication (VLC) can provide a short range data transmission. Their properties are suitable for the ADAS (Advanced Driving Assistance System) applications on smartphones. In this paradigm, a smartphone need to connect with the sensitive information of a vehicle. The quality of this data exchange is an important issue. To do this, we design and implement a VLC system that uses two components: a modified reading light and an USB optical transceiver. In our paradigm, these two components are fixed inside a vehicle. This constrained mobility is suitable for our VLC system. Comparing RF communication, our VLC system provides a stable short range communication with limited transmission power and LOS property. This is an ideal candidate to achieve a stable, secure and private data transmission for ADAS applications. In this work, a VLC for prototype based on commercial LED is presented and tested. This experimental study has proved that our VLC prototype is realistic for providing a good enough quality of the data link and can run on resource-constrained platforms.
