The Networked Systems group works on building internet and communications technologies for a performant, sustainable and trustworthy digitalized society. Our research spans from software development, to algorithm and protocol design, to systems engineering, with the aim to push the envelope in internet, 6G, and IoT. Our group comprises four labs, namely on: (1) internet science, (2) network optimization, (3) exreme IoT, and (4) visual light communications. We are a section within the Department of Software Technology of the Faculty Electrical Engineering, Mathematics, and Computer Science of Delft University of Technology and we actively participate within the Do IoT fieldlab.
