Paper Abstract

Traditional Visible Light Communication (VLC) based indoor positioning algorithm needs long time for positioning processing. An improved k-means method is presents in this paper which allows the positioning terminal to receive the signal strength information generated by different LEDs, and the improved k-means method is implemented to establish the fingerprint database. The triangle positioning method will be firstly used to roughly determine the position, and then adopt the fingerprint matching method for accurate locating. Simulation results show that compared with the traditional fingerprint-based method, the improved k-means method has improved the computing efficiency of positioning process.
