High Precision Indoor VLC positioning Techniques

Abstract

Visible light communication(VLC) has been gaining a good deal of attraction because of its ability to use the transmitter -LED’s for both communication and illumination. VLC can be used in an environment where wireless communication is not preferred such as hospitals and other chemical plants. Although Global positioning system (GPS) is generally acknowledged, within an indoor environment, VLC has the ability to provide results with better accuracy as it avoids attenuation and blocking. VLC positioning techniques such as Received signal strength (RSS) based trilateration and proximity method are currently being implemented, however the new proposed model which is the weighted k nearest neighbour(Wk-NN) models provides us with a better accuracy than some of the existing methods.
