As a vital metric of information timeliness, Age of Information (AoI) is important for real-time
applications in Internet of Things (IoT), such as health monitoring. To satisfy these …

It is well known that multi-modal services, including video, audio, and haptic signals, aim to
provide immersive experience with low latency and high reliability. Although multi-modal …

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 …

We introduce a new semantic communication mechanism-SemanticRL, whose key idea is to
preserve the semantic information instead of strictly securing the bit-level precision. Unlike …

We consider a resource-constrained IoT network, where multiple users make on-demand
requests to a cache-enabled edge node to send status updates about various random …

This article explores the significance of the timeliness of information in the context of fifth
generation (5G) nonterrestrial networks (NTNs). As 5G technology continues to evolve, its …

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 …

Power control policies that minimize the weighted combination of age of information (AoI)
and total energy consumption are studied in this paper. It is assumed that the status update …

Many emerging applications in edge computing require processing of huge volumes of data
generated by end devices, using the freshest available information. In this paper, we …

This paper considers the design of age-optimal packet scheduling policies in networks with
delayed feedback, long-term resource constraint and various packet arrival models. The …
