Ambient intelligence (AmI) represents the future vision of intelligent computing that can bring
intelligence to our daily life through various domains. In such applications, AmI is often …

We consider an information update system where an information receiver requests updates
from an information provider in order to minimize its age of information. The updates are …

In emerging fifth generation and beyond wireless communication systems, communication
nodes are expected to support information flows that are freshness-sensitive, along with …

Freshness of information is an important requirement in many real-time applications. It is
measured by a metric called the age of information (AoI), defined as the time elapsed since …

We consider a system consisting of a server, which receives updates for N files according to
independent Poisson processes. The goal of the server is to deliver the latest version of the …

This article investigates the information freshness of Industrial Internet of Things (IIoT)
systems, where each IoT device makes a partial observation of a common target and …

We consider a distributed IoT network, where each node wants to minimize its own age of
information and there is a cost to make any transmission. A collision model is considered …

This letter studies the “age of information”(AoI) in a multi-source status update system where
N active sources each send updates of their time-varying process to a monitor through a …

We consider an information update system where an information receiver requests updates
from an information provider in order to minimize its age of information. The updates are …

The energy harvesting D2D-enabled cellular network (EH-DCN) has emerged as a
promising approach to address the issues of energy supply and spectrum utilization. Most of …
