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 …

Timely status updates are crucial to enabling applications in the massive Internet of Things
(IoT). This paper measures the data-freshness performance of a status update system with …

Consider an energy harvesting (EH) sensor that continuously monitors a system and sends
time-stamped status update to a destination. The sensor harvests energy from nature and …

Age of Information (AoI) is a fundamentally important metric to characterize the freshness of
information in real-time Internet-of-Things (IoT) monitoring systems. Another important metric …

As 5G and Internet-of-Things (IoT) are deeply integrated into vertical industries such as
autonomous driving and industrial robotics, timely status update is crucial for remote …

Age of information (AoI) is a key performance metric for the Internet of things (IoT). Timely
status updates are essential for many IoT applications; however, they often suffer from harsh …

This paper considers a multi-source updating system in which a transmitter node powered
by energy harvesting (EH) sends status updates about multiple sources of information to a …

This paper considers a real-time status update system in which an energy harvesting (EH)-
powered transmitter node observes some physical process, and sends its sensed …

A status updating system is considered in which data from multiple sources are sampled by
an energy harvesting sensor and transmitted to a remote destination through an erasure …

In this paper, we study the information freshness of short-packet communication in wireless
networks, where a base station (BS) sends time-sensitive status updates to users via …
