Revisit the Arimoto-Blahut algorithm: New Analysis with Approximation
Michail Fasoulakis, Konstantinos Varsos, Apostolos Traganitis
By the seminal paper of Claude Shannon \cite{Shannon48}, the computation of the capacity of a discrete memoryless channel has been considered as one of the most important and funda…
Semantics-Aware Active Fault Detection in Status Updating Systems
George Stamatakis, Nikolaos Pappas, Alexandros Fragkiadakis +1
With its growing number of deployed devices and applications, the Internet of Things (IoT) raises significant challenges for network maintenance procedures. In this work we address…
Autonomous Maintenance in IoT Networks via AoI-driven Deep Reinforcement Learning
George Stamatakis, Nikolaos Pappas, Alexandros Fragkiadakis +1
Internet of Things (IoT) with its growing number of deployed devices and applications raises significant challenges for network maintenance procedures. In this work, we formulate a…
Control of Status Updates for Energy Harvesting Devices that Monitor Processes with Alarms
George Stamatakis, Nikolaos Pappas, Apostolos Traganitis
In this work, we derive optimal transmission policies in an energy harvesting status update system. The system monitors a stochastic process which can be either in a normal or in a…
Optimal Policies for Status Update Generation in a Wireless System with Heterogeneous Traffic
George Stamatakis, Nikolaos Pappas, Apostolos Traganitis
A large body of applications that involve monitoring, decision making, and forecasting require timely status updates for their efficient operation. Age of Information (AoI) is a ne…
Jamming in multiple independent Gaussian channels as a game
Michail Fasoulakis, Apostolos Traganitis, Anthony Ephremides
We study the problem of \emph{jamming} in multiple independent \emph{Gaussian channels} as a zero-sum game. We show that in the unique Nash equilibrium of the game the best-respons…
