Seminar: Game theoretic analysis of Age of Information for Slotted ALOHA access with capture

On 29th March 2023 at 10:00h the CTTC will host the seminar “Game theoretic analysis of Age of Information for Slotted ALOHA access with capture”. In this seminar Prof. Leonardo Badia will present:


Age of Information (AoI) is a useful performance metric in multi-agent scenarios with distributed access envisioned for 6G communication systems, such as URLLC employed in diverse mission-critical applications like industrial automation, intelligent transportation, telemedicine, Tactile Internet, Extended/Virtual/Augmented Reality, and the Metaverse. In this paper, we apply game theory to extend some results quantifying AoI in the case of random-based medium access protocols to the case of ALOHA with capture. Uncoordinated transmissions are often considered inefficient and unstable from a game theoretic perspective, because the players (i.e., the transmitters) want to maximize their individual utility and tend to be very aggressive, which causes collisions.

We show that, if the objective shifts to AoI, and advanced access protocols with multiple packet reception are considered, the resulting equilibrium can become more efficient and allows for a distributed implementation. This suggests interesting consequences for practical applications in future communication systems with multiple distributed interactive agents.


Leonardo Badia received his Msc. and PhD degree from the University of Ferrara, Italy. He held previous positions with the Department of Engineering of the University of Ferrara, the RST Labs (now Wireless@KTH) at the Royal Institute of Technology (KTH), Stockholm, Sweden, and the IMT Lucca Institute for Advanced Studies, Lucca, Italy. In March 2011 he joined the faculty of the University of Padova as an Assistant Professor. In 2016, he was promoted to Associate Professor. He is author of more than 200 scientific papers published in international peer-reviewed journals or conferences. He is a frequent reviewer for several periodicals in the areas of telecommunications, computer engineering and networking. His research interests are in the broad area of mathematical optimization for communication networks, including: analysis of transmission protocols via Markov models; cross-layer optimization of routing/scheduling/resource allocation; Age-of-Information; models for energy harvesting; applications of game theory to communication networks.

This talk is open to whoever interested from the research community
