In recent years, the increasing demand to see the status of objects over the Internet leads to
an increase in the number of Internet of Things (IoT) applications. The unique nature of IoT …

This article comprehensively surveys the area of age of information (AoI) in the wireless
networks and focuses on categorising and reviewing the current progress on AoI from an …

This paper characterizes the structure of the Age of Information (AoI)-optimal policy in
wireless powered communication systems while accounting for the time and energy costs of …

Scheduling updates from remote sensors is a key task for the internet of things (IoT). In this
context, the mathematical concept of age of information is often used to capture the …

We consider a status update system where multiple sensors communicate timely information
about various random processes to a sink. The sensors share orthogonal sub-channels to …

Age of information (AoI) is an effective measure of the information freshness for wireless
networked control systems (WNCSs). However, the AoI performance for a closed loop of …

In this letter, we consider the requirement of information freshness in covert communications
for the first time. With artificial noise (AN) generated from a full-duplex (FD) receiver, we …

The upcoming satellite-based Internet of Things (S-IoT) has the capability to provide timely
status updates to massive terrestrial user equipments (UEs) via non-orthogonal multiple …

In this work, we study age-optimal scheduling with stability constraints in a multiple access
channel with two heterogeneous source nodes transmitting to a common destination. The …

The problem of scheduling packets from multiple sources over unreliable channels has
attracted much attention due to its great practicability in the Internet of things systems. Most …
