The world is often stricken by catastrophic disasters. On-demanddrone-mounted visible light communication (VLC) networks are suitable formonitoring disaster-stricken areas for leveraging disaster-response operations.The concept of an image sensor-based VLC has also attracted attention in therecent past for establishing stable links using unstably moving drones.However, existing works did not sufficiently consider the one-to-many imagesensor-based VLC system. Thus, this paper proposes the concept of a one-to-manyimage sensor-based VLC between a camera and multiple drone-mounted LED lightswith a drone-positioning algorithm to avoid interference among VLC links.Multiple drones are deployed on-demand in a disaster-stricken area to monitorthe ground and continuously send image data to a camera with image sensor-basedvisible light communication (VLC) links. The proposed idea is demonstrated withthe proof-of-concept (PoC) implemented with drones that are equipped with LEDpanels and a 4K camera. As a result, we confirmed the feasibility of theproposed system.
