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 …

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 …

Age of information (AoI) was introduced in the early 2010s as a notion to characterize the
freshness of the knowledge a system has about a process observed remotely. AoI was …

We examine multiple independent sources providing status updates to a monitor through
simple queues. We formulate an age of information (AoI) timeliness metric and derive a …

In this paper, we consider the cellular Internet of unmanned aerial vehicles (UAVs), where
UAVs sense data with onboard sensors for multiple sensing tasks and transmit the data to …

A source provides status updates to monitors through a network with state defined by a
continuous-time finite Markov chain. An age of information (AoI) metric is used to …

In this paper, we investigate scheduling policies that minimize the age of information in
single-hop queueing systems. We propose a Last-Generated, First-Serve (LGFS) scheduling …

Information updates in multihop networks such as Internet of Things (IoT) and intelligent
transportation systems have received significant recent attention. In this paper, we minimize …

Age of Information (AoI) has become an important concept in communications, as it allows
system designers to measure the freshness of the information available to remote monitoring …

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 …
