When Fresh Information Is Not Enough: Age-of-Actuation-Optimal Scheduling for Energy-Harvesting Actuators
Ali Nikkhah, Anthony Ephremides, Nikolaos Pappas
We study transmission scheduling in an energy-harvesting actuation system where an actuation requires both a received update and available energy. While age of information (AoI) me…
Innovation-Based Sampling for New Information
Jiping Luo, Anthony Ephremides, Nikolaos Pappas
This work introduces innovation-based sampling of continuous stochastic processes, in which a sample is generated only when the process reveals ``sufficiently new'' information rel…
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…
