From Information Freshness to Semantics of Information and Goal-oriented Communications
Wireless networks are evolving to cater to emerging cyber-physical and mission-critical interactive systems, such as swarm robotics, self-driving cars, and the smart Internet of Things. A fundamental shift in thinking is necessary to satisfy the requirements for real-time communication, autonomous decision-making, and efficient distributed processing. In this talk, we will focus on the freshness and value of information, and we will present some initial results and ongoing works on semantics-aware goal-oriented communication.
Nikolaos Pappas (Senior Member, IEEE) received a B.Sc. degree in computer science, a B.Sc. degree in mathematics, an M.Sc. degree in computer science, and a Ph.D. degree in computer science from the University of Crete, Greece, in 2005, 2012, 2007, and 2012, respectively. From 2005 to 2012, he was a Graduate Research Assistant with the Telecommunications and Networks Laboratory, Institute of Computer Science, Foundation for Research and Technology—Hellas, Heraklion, Greece, and a Visiting Scholar with the Institute of Systems Research, University of Maryland at College Park, College Park, MD, USA. From 2012 to 2014, he was a postdoctoral Researcher with the Department of Telecommunications, CentraleSupélec, Gif-sur-Yvette, France. He is currently an Associate Professor at the Department of Computer and Information Science at Linköping University, Linköping, Sweden. His main research interests include the field of wireless communication networks with an emphasis on semantics-aware communications, energy harvesting networks, network-level cooperation, age of information, and stochastic geometry. Dr. Pappas has served as the Symposium Co-Chair of the IEEE International Conference on Communications in 2022 and the IEEE Wireless Communications and Networking Conference in 2022. From 2013 to 2018, he was an Editor of the IEEE COMMUNICATIONS LETTERS. He was a Guest Editor of the IEEE INTERNET OF THINGS JOURNAL on “Age of Information and Data Semantics for Sensing, Communication and Control Co-Design in IoT”. He is also an Editor of the IEEE TRANSACTIONS ON COMMUNICATIONS, the IEEE Transactions on Machine Learning in Communications and Networking, the IEEE/KICS JOURNAL OF COMMUNICATIONS AND NETWORKS. He is area editor of the IEEE OPEN JOURNAL OF THE COMMUNICATIONS SOCIETY and an Expert Editor for invited papers of the IEEE COMMUNICATIONS LETTERS. He is guest editor of the IEEE Network on “Tactile Internet for a cyber-physical continuum”. He has co-authored a monograph on Age of Information, and he is the leading editor of a book on “Age of Information: Foundations and Applications” published by Cambridge University Press. He has appeared in the Top 2% scientists list, single year impact, in the area of Networking and Telecommunications for the last three years. He is the principal investigator of the project “Semantics-Empowered Communication for Networked Intelligent Systems” funded by the Swedish Research Council, and he is the main PI of five more projects related to the semantics of information funded by other national and EU sources.
