Remote Tracking with State-Dependent Sensing in Pull-Based Systems: A POMDP Framework
Jiapei Tian, Abolfazl Zakeri, Marian Codreanu +1
We consider real-time remote tracking of a Markov source observed by multiple heterogeneous sensors with state-dependent sensing accuracy, motivated by distributed camera networks…
Goal-Oriented Remote Tracking Through Correlated Observations in Pull-based Communications
Abolfazl Zakeri, Mohammad Moltafet, Marian Codreanu
We address the real-time remote tracking problem in a status update system comprising two sensors, two independent information sources, and a remote monitor. The status updating fo…
Real-time Tracking in a Status Update System with an Imperfect Feedback Channel
Saeid Sadeghi Vilni, Abolfazl Zakeri, Mohammad Moltafet +1
We consider a status update system consisting of a finite-state Markov source, an energy-harvesting-enabled transmitter, and a sink. The forward and feedback channels between the t…
Semantic-aware Sampling and Transmission in Energy Harvesting Systems: A POMDP Approach
Abolfazl Zakeri, Mohammad Moltafet, Marian Codreanu
We address the problem of real-time remote tracking of a partially observable Markov source in an energy harvesting system with an unreliable communication channel. We consider bot…
