Um Protocolo de Roteamento Dinâmico para Redes de Comunicação por Luz Visível

Visible Light Communication (VLC) presents several challenges such as interference and blockages created by obstacles. At the same time, many environments offer a rich infrastructure of light sources that can be used to aid end-to-end communication. In this paper, D-VLC is a dynamic routing protocol. D-VLC reacts to communication interruptions by building alternative routes in the visible light network without prior knowledge of the topology or even the devices that compose it. The new protocol was implemented and evaluated in a real environment using the OpenVLC embedded platform. The results show that, using D-VLC, the network was able to adapt to dynamic changes in communication, such as shadows and obstacles, with network usage overload of less than 10%.
