The Networked Systems group works on building Internet and communication technologies for a performant, sustainable, and trustworthy digitalized society. Our research spans from software development, to algorithm/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) extreme IoT, and (4) sustainable sensing and communication. 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.
