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…
Optimal Semantic-aware Sampling and Transmission in Energy Harvesting Systems Through the AoII
Abolfazl Zakeri, Mohammad Moltafet, Marian Codreanu
We study a real-time tracking problem in an energy harvesting status update system with a Markov source and an imperfect channel, considering both sampling and transmission costs.…
Query-Age-Optimal Scheduling under Sampling and Transmission Constraints
Abolfazl Zakeri, Mohammad Moltafet, Markus Leinonen +1
This letter provides query-age-optimal joint sampling and transmission scheduling policies for a heterogeneous status update system, consisting of a stochastic arrival and a genera…
Minimizing the AoI in Resource-Constrained Multi-Source Relaying Systems: Dynamic and Learning-based Scheduling
Abolfazl Zakeri, Mohammad Moltafet, Markus Leinonen +1
We consider a multi-source relaying system where independent sources randomly generate status update packets which are sent to the destination with the aid of a relay through unrel…
Online Service Provisioning in NFV-enabled Networks Using Deep Reinforcement Learning
Ali Nouruzi, Abolfazl Zakeri, Mohamad Reza Javan +3
In this paper, we study a Deep Reinforcement Learning (DRL) based framework for an online end-user service provisioning in a Network Function Virtualization (NFV)-enabled network.…
Minimizing AoI in Resource-Constrained Multi-Source Relaying Systems with Stochastic Arrivals
Abolfazl Zakeri, Mohammad Moltafet, Markus Leinonen +1
We consider a multi-source relaying system where the sources independently and randomly generate status update packets which are sent to the destination with the aid of a bufferaid…
Proactive and AoI-aware Failure Recovery for Stateful NFV-enabled Zero-Touch 6G Networks: Model-Free DRL Approach
