Abstract Visible Light Communication (VLC) presents several challenges, such as interference and blockages created by obstacles. At the same time, several environments offer a rich infrastructure of light sources, which can be used to aid end-to-end communication. In this work, we present DYRP-VLC, a dynamic routing protocol. DYRP-VLC reacts to communication interruptions, constructing alternative routes in the network of visible light, without the need for previous knowledge of the topology or even of the devices that comprise it. We implemented and evaluated the new protocol in a real-world environment using the OpenVLC embedded platform. Our results show that, by using DYRP-VLC, the network was able to form wireless ad-hoc networks and to adapt to dynamic changes in communication such as shadows and obstacles. More in deep, the protocol we propose presents low overhead (
