Low-Complexity Visible Light Networking with LED-to-LED Communication

16 Jan

Domenico Giustiniano, Senior Researcher and Lecturer, ETH Zurich, Switzerland

In-house Presentation

Visible Light Communication (VLC) is an emerging technology in which Light Emitting Diodes (LEDs) transport information wirelessly, using the visible light spectrum. While most of the research on VLC has focused on wideband white LEDs used in ambient illumination, narrowband and colored LEDs have received little attention. Short-range free-space optical communication based on narrowband LEDs as visible light transmitters and receivers enable a variety of applications, a scenario we refer as LED-to-LED communication. In this work, we introduce the communication and networking protocols of LED-to-LED communication. Our work addresses fundamental challenges such as efficient collision detection medium access protocol and elimination of light flicker. We build a prototype and demonstrate bi-directional data exchange in a network of up to four LEDs. We further study the trade-offs in the system design and measure the achievable bit-rate and transmission distances

Who is Domenico Giustiniano?

Domenico Giustiniano is Senior Researcher and Lecturer at ETH Zurich. Before joining ETH, he was a Post-Doctoral Researcher at Disney Research Zurich and at Telefonica Research Barcelona. He holds a PhD in Telecommunication Engineering from the University of Rome Tor Vergata. He also worked as research assistant in other labs, such as the Hamilton Institute in Ireland; Intel Lab of CMU Pittsburgh in USA; University of Palermo in Italy; and the University of Ulm in Germany. His research interests are in the wide area of wireless and sensor networks, including more recently emerging areas such as cloud-based opportunistic communication and UAVs network.
