Abstract

Visible light communication, as a promising future wireless communication technology, has been considered as an attractive solution for indoor positioning systems. An indoor visible light positioning system based on cooperative localization is proposed to support illumination and positioning simultaneously. By cooperation among agents, the positioning system can work in a harsh environment, where a two-light-emitting diodes positioning scheme is proposed as an example specifically. The Bayesian framework and factor graph are introduced to describe the location problems, while the sum-product algorithm is adopted to deal with the positioning process and determine the receivers’ location. Moreover, simulations are carried out to demonstrate that the proposed system can achieve centimeter-scale positioning accuracy, and the feasibility is also verified.
