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 …

In this work we address a problem of active fault detection in an IoT scenario, whereby a
monitor probes a remote device in order to detect faults and acquire fresh information …

With the development of the Internet of Things, the sensor usage has been elevated to a
new level, and it becomes more crucial to maintain reliable sensor networks. In this article …

With its growing number of deployed devices and applications, the Internet of Things (IoT)
raises significant challenges for network maintenance procedures. In this work, we address …

Age of Information (AoI) is a popular metric of data freshness, however, it neglects the
usability of data. In light of this, we introduce a new metric, Age of Usage Information (AoUI) …

Semantic status update communication (SSUC) is envisioned to provide content-aware and
energy efficient information delivery. In this paper, we introduce a new metric in the SSUC …

The intricate interplay of source dynamics, unreliable channels, and staleness of information
has long been recognized as a significant impediment for the receiver to achieve accurate …

Optimizations premised on open-loop metrics such as Age of Information (AoI) indirectly
enhance the system's decision-making utility. We therefore propose a novel closed-loop …

In this work, we study the age-optimal status update strategy for a large number of sensors in
a wireless system with multiple heterogeneous unreliable channels. Particularly, we first …

The popularization of the automated fleet requires a reliable transmission of In-vehicle Local
Area Network (LAN) with high mobility under complex environment. Therefore, In-vehicle …
