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…
From Information Freshness to Semantics of Information and Goal-oriented Communications
Jiping Luo, Erfan Delfani, Mehrdad Salimnejad +1
Future wireless networks must support real-time, data-driven cyber-physical systems in which communication is tightly coupled with sensing, inference, control, and decision-making.…
So Timely, Yet So Stale: The Impact of Clock Drift in Real-Time Systems
Mehrdad Salimnejad, Nikolaos Pappas, Marios Kountouris
In this paper, we address the problem of timely delivery of status update packets in a real-time communication system, where a transmitter sends status updates generated by a sourc…
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…
Age of Information Versions: a Semantic View of Markov Source Monitoring
Mehrdad Salimnejad, Marios Kountouris, Anthony Ephremides +1
We consider the problem of real-time remote monitoring of a two-state Markov process, where a sensor observes the state of the source and makes a decision on whether to transmit th…
Version Innovation Age and Age of Incorrect Version for Monitoring Markovian Sources
Mehrdad Salimnejad, Marios Kountouris, Anthony Ephremides +1
In this paper, we propose two new performance metrics, coined the Version Innovation Age (VIA) and the Age of Incorrect Version (AoIV) for real-time monitoring of a two-state Marko…
State-aware Real-time Tracking and Remote Reconstruction of a Markov Source
Mehrdad Salimnejad, Marios Kountouris, Nikolaos Pappas
The problem of real-time remote tracking and reconstruction of a two-state Markov process is considered here. A transmitter sends samples from an observed information source to a r…
Real-time Remote Reconstruction of a Markov Source and Actuation over Wireless
Mehrdad Salimnejad, Marios Kountouris, Nikolaos Pappas
In this work, we study the problem of real-time tracking and reconstruction of an information source with the purpose of actuation. A device monitors an -state Markov process an…
Real-time Reconstruction of Markov Sources and Remote Actuation over Wireless Channels
Mehrdad Salimnejad, Marios Kountouris, Nikolaos Pappas
In this work, we study the real-time tracking and reconstruction of an information source with the purpose of actuation. A device monitors the state of the information source and t…
