Author Affiliations +
Indoor positioning based on visible light communication (VLC) technology has become a very popular research topic recently. This paper provides an overview of different VLC based indoor positioning techniques and their performance. Three schemes of location estimation together with their mechanisms are introduced. We then present a detailed comparison on their performances in terms of accuracy, space dimension and complexity. We further discuss a couple of factors that would affect the performance of each of these positioning systems, including multipath reflections and synchronization. Finally, conclusions and future prospects of research are addressed.
