A Visible Light Communication Positioning Mechanism in Industrial Logistics Management

In last decade, LEDs are popularly employed in our daily life due to its own characteristics. As LEDs have many advantages such as high tolerance to humidity, long usage lifetime, and low power consumption, it has been employed in our daily life in various ways, (car lamps and lights in vehicles, roadside signal lights, indoor lighting systems, etc.). Moreover, LEDs can also be employed for wireless data communications, namely visible light communication (VLC), which is a fast-growing technology to provide data communication using low-cost and energy efficient light-emitting diode (LED) and photodiodes. Therefore, it draws lots of attention to the industrial communication systems and expected to bring benefits such as reduce deployment and maintenance cost after employed. However, in the industrial logistics systems, it will be required to reach "high accuracy position" and "reliability communication control" to satisfy their transportation goal. Hence, we proposed a visible light positioning mechanism, namely IMLE approach, to achieve high accuracy and reliability issues in industrial logistics system. We currently working on implemented this algorithm in simulation.
