Optimal Sampling and Actuation for Real-Time Monitoring of Markov Sources
Mehrdad Salimnejad, Anthony Ephremides, Marios Kountouris +1
This paper studies efficient data management and timely information dissemination for real-time monitoring of an N-state Markov process, with the objective of enabling accurate sta…
Real-Time Remote Monitoring of Correlated Markovian Sources
Mehrdad Salimnejad, Marios Kountouris, Nikolaos Pappas
We investigate real-time tracking of two correlated stochastic processes over a shared wireless channel. The joint evolution of the processes is modeled as a two-dimensional discre…
Affine Frequency Division Multiplexing: From Communication to Sensing
Ali Bemani, Nassar Ksairi, Marios Kountouris
Affine Frequency Division Multiplexing (AFDM) has been proposed as an effective waveform for achieving the full diversity of doubly-dispersive (delay-Doppler) channels. While this…
From OFDM to AFDM: Enabling Adaptive Integrated Sensing and Communication in High-Mobility Scenarios
Haoran Yin, Yanqun Tang, Jun Xiong +7
Integrated sensing and communication (ISAC) is a key feature of next-generation wireless networks, enabling a wide range of emerging applications such as vehicle-to-everything (V2X…
Age of Information-Aware Cognitive Shared Access Networks with Energy Harvesting
Georgios Smpokos, Dionysis Xenakis, Marios Kountouris +1
This study investigates a cognitive shared access network with energy harvesting capabilities operating under Age of Information (AoI) constraints for the primary user. Secondary t…
Agoran: An Agentic Open Marketplace for 6G RAN Automation
Ilias Chatzistefanidis, Navid Nikaein, Andrea Leone +5
Next-generation mobile networks must reconcile the often-conflicting goals of multiple service owners. However, today's network slice controllers remain rigid, policy-bound, and un…
