Space and Satellite Networking


Context: Unlike traditional mobile networks, space and satellite networks (SSNs) are challenged by high delay due to signal propagation, and disruptions due to planet rotation and resource limitations.

Challenge: Internet-like data handling is not always a good fit for SSNs. Instead, novel networking architectures paradigms are being proposed to leverage accurate planning based on available information of the connectivity and resources (proactive vision) but also to dynamically learn and distribute the intelligence to survive faults and unexpected events (reactive vision). Taking the best out of very expensive and complex space systems sits at the crossroads of these visions.

Methods: In this seminar we explore an extensive variety of applied state-of-the-art models, algorithms and artificial intelligence approaches enabling the realization of future SSN including mega-constellations and deep-space missions. The objective is to practice and to refine the skills of scientific presentation, and scientific argumentation. We are looking for critical/creative thinking on the applicability of the approaches.


A weekly time slot will be defined, which might be used on an on-demand basis for meetings held remotely via Zoom. The precise weekly time slot will be fixed once the participants' constraints are known.

Kick-off meeting: Thu, Nov 5 at 2:00 pm (Zoom link available in the materials page).
