Sunlight for wireless communication | Marco Zúñiga
Apr 06, 2023 | 4:00 PM CET
We, humans, already use 50% more energy moving information than moving airplanes around the world. Communication is central to our societies but is taking a toll on the earth.
We want to use a free, abundant, and natural resource for wireless communication: sunlight. Similar to the way you can use a mirror to communicate by reflecting light, our aim is to change the surfaces of objects to control their reflection properties to send information, but without noticing any flicker!
In this manner, objects will be able to talk to each other using daylight, an eco-friendly solution. In this talk, we will present some of our recent work on this exciting area and its potential applications.
A world that communicates through natural light. That’s the goal.

He obtained his Ph.D. and MSc in Electrical Engineering from the University of Southern California, Los Angeles, and his BSc in Electronics Engineering from the Pontificia Universidad Católica del Perú.
Dr. Zúñiga has more than 60 scientific publications and has received three Best Paper Awards, five Best Paper Runner-ups, and an Accenture Innovation Award in 2017. Two of his publications are the 3rd and 16th most cited papers in the ACM Transactions on Sensor Networks. Dr. Zúñiga has also been invited to present his work on "Sunlight for wireless communication" at the Innovation Expo 2018, a flagship event organized by six Dutch Ministries to showcase Dutch innovation to the world.
Trust Management in Social Internet of Things | Barbora Buhnova
May 04, 2023 | 4:00 PM CET
Digitalization is leading us towards a future where people, processes, data and things are not only interacting with each other, but might start forming societies on their own. In these dynamic systems, converging towards Social Internet of Things (SIoT), trust management on the level of human-to-thing as well as thing-to-thing interaction becomes an essential ingredient to supervise safe and secure progress of our digitalized future. In this talk, we will look into the essential elements of trust management in complex digital ecosystems and SIoT, including trust assessment and its influencing factors (e.g., feeling vulnerable), trust propagation (e.g., via reputation), and trust updates (e.g., via dynamic certification schemes). We will give an overview of the current open discussions about the trust management strategies and discuss their risks and related trust attacks (e.g, self-promotion or whitewashing).
Barbora Buhnova is an Associate Professor and Vice-Dean at Masaryk University (MU), Faculty of Informatics (FI MU) in Brno, Czech Republic. Following her research career in Germany and Australia, she now leads multiple research teams at Faculty of Informatics MU (software architecture) and Czech CyberCrime Centre of Excellence C4e (critical infrastructures), with special emphasis on trust management in autonomous ecosystems. She is a Steering Committee member of the International Conference on Software Architecture (ICSA) and has been involved in organization of numerous leading conferences (e.g. in OC of ICSE, ESEC-FSE, ASE). She acts as a reviewer and (guest) editor in multiple journals (e.g. IEEE TSE, Springer EMSE, Elsevier SCP, Elsevier JSS, Springer SoSyM, Wiley SME), and is member of the IEEE TSE Review Board. Next to her academic activities, she is the chair of the Association of Industrial Partners at FI MU (with 30+ companies), and is a Co-Founding and Governing Board member of Czechitas, a non-profit organisation aiming at making IT skills more accessible to youth and women (with 30,000+ graduates).
