Description du projet
Vers des dispositifs IdO sans batterie
La demande de services de données sans fil et de sources d’énergie augmente et cette poussée est largement due aux progrès de la technologie des dispositifs IdO. Cependant, comme le nombre de dispositifs IdO devrait atteindre plusieurs dizaines de milliards dans le monde entier au cours des prochaines années, il y a de plus en plus de préoccupations concernant les éléments chimiques libérés dans l’environnement des batteries éliminées de manière inappropriée. Financé par le programme Actions Marie Skłodowska-Curie, le projet RISA-VLC ouvrira la voie à des dispositifs IdO sans batterie. En s’appuyant sur des surfaces réfléchissantes intelligentes (qui reconfigurent la propagation électromagnétique), les chercheurs veulent modifier les canaux de propagation des communications par lumière visible.
Objectif
The vast development of smart communication devices for the Internet of Things (IoT) is incurring an ever-increasing demand of wireless data services and energy sources. It is expected to witness a growth of connected IoT devices in the next few years, reaching up to tens of billions. Currently, these devices rely on batteries for its operation, but the battery recycling is a delicate matter that has a negative environmental impact due to their chemical components. Thus, it is reasonable to think that future communication systems must comply with energy-efficiency standards by minimizing the use of batteries, and then reduce its carbon footprint.
The main objective of RISA-VLC is to enable battery-free IoT devices by engineering, thanks to reflective intelligent surfaces (RIS), the propagation channel of the Visible Light Communication (VLC) technology. To this end, I will retrofit the pervasive deployment of indoor LEDs to provide a robust communication link and an enhanced light power received at IoT devices. In the outgoing phase at University of Virginia I will characterize RIS to perform the additional channel path, which I will also model. Then, I will study its effect in the communication and lighting performance. In the return phase at the Universidad Carlos III de Madrid I will research novel signal-processing and communication techniques to exploit the manageable channel proposed during the outgoing phase. Besides, I will establish guidelines for creating battery-free VLC-enabled IoT devices. The training activities proposed are fundamental for the achievement of RISA-VLC and my personal career goals.
RISA-VLC guarantees a three-way transfer of knowledge since it combines my past experience in theoretical VLC techniques and VLC prototyping, with supervisors' expertise on optimization of systems, VLC reflection exploitation and advanced signal processing and communication techniques.
