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…
Age of Incorrect Information for Generic Discrete-Time Markov Sources
Konstantinos Bountrogiannis, Anthony Ephremides, Panagiotis Tsakalides +1
This work introduces a framework for analyzing the Age of Incorrect Information (AoII) in a real-time monitoring system with a generic discrete-time Markov source. We study a noisy…
Semantics in Actuation Systems: From Age of Actuation to Age of Actuated Information
Ali Nikkhah, Anthony Ephremides, Nikolaos Pappas
In this paper, we study the timeliness of actions in communication systems where actuation is constrained by control permissions or energy availability. Building on the Age of Actu…
Optimizing Version Innovation Age for Monitoring Markovian Source in Energy-Harvesting Systems
Mehrdad Salimnejad, Anthony Ephremides, Marios Kountouris +1
We study the real-time remote tracking of a two-state Markov process by an energy harvesting source. The source decides whether to transmit over an unreliable channel based on the…
Variable-Length Stop-Feedback Coding for Minimum Age of Incorrect Information
Konstantinos Bountrogiannis, Ioannis Papoutsidakis, Anthony Ephremides +2
The Age of Incorrect Information (AoII) is studied within the context of remote monitoring a Markov source using variable-length stop-feedback (VLSF) coding. Leveraging recent resu…
