Over the last 20 years, the rise of IoT and cloud computing has driven the need for massive global deployment of sensors to feed databases and improve the accuracy of analysis algorithms. To meet these demands, new networks based on ISM frequency bands have been deployed. We have therefore fully understood these technologies in order to guarantee maximum quality for our products but also to offer fair advice in a sector where abuse of language and promises of performance are commonplace. However, the growing number of objects emitting under the gigahertz frequency raises a doubt about the impact on the health of living beings. Therefore, coupling the non-invasive aspect of VLC with the Internet of Things would not only reduce the risks for human beings but also limit the saturation of radio bands. Nevertheless, today's techniques mainly consist in the realization of systems broadcasting information from a single source to several receivers, which is the opposite of the IoT paradigm. In this study, we have therefore realized a new design based on VLC that implements a star 3 network topology. This system, based on a hub with one or more cameras as photoreceivers, is optimized for more autonomy. Thus, the transmission rate can be managed dynamically without being known by the other elements of the system.
