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 …

Communication systems to date primarily aim at reliably communicating bit sequences.
Such an approach provides efficient engineering designs that are agnostic to the meanings …

We summarize recent contributions in the broad area of age of information (AoI). In
particular, we describe the current state of the art in the design and optimization of low …

Abstract In Industrial Internet of Things (IIoT), a large volume of data is collected periodically
by IoT devices, and timely data routing and processing are important requirements. Age of …

The safety of connected automated vehicles (CAVs) relies on the reliable and efficient raw
data sharing from multiple types of sensors. The 5G millimeter wave (mmWave) …

In this paper, we consider a wireless network enabled by multiple unmanned aerial vehicles
(UAVs), which observe physical processes and transmit status updates to a monitor node …

The freshness of status information is of great importance for time-critical Internet-of-Things
(IoT) applications. A metric measuring status freshness is the Age of Information (AoI), which …

One of the critical use cases for prospective fifth generation (5G) cellular systems is the
delivery of the state of the remote systems to the control center. Such services are relevant …

Abundant real-time applications over Internet of Things (IoT) have imperative demands on
timely information. Compared to average Age of Information (AoI), distribution of AoI …

We study a general setting of gossip networks in which a source node forwards its
measurements (in the form of status updates) about some observed physical process to a …
