Age of information: An introduction and survey

RD Yates, Y Sun, DR Brown, SK Kaul… - IEEE Journal on …, 2021 - ieeexplore.ieee.org
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 …

Age of information: A new concept, metric, and tool

A Kosta, N Pappas, V Angelakis - Foundations and Trends® …, 2017 - nowpublishers.com
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 …

[图书][B] Age of information: A new metric for information freshness

Y Sun, I Kadota, R Talak, E Modiano - 2022 - books.google.com
Information usually has the highest value when it is fresh. For example, real-time knowledge
about the location, orientation, and speed of motor vehicles is imperative in autonomous …

The age of information: Real-time status updating by multiple sources

RD Yates, SK Kaul - IEEE Transactions on Information Theory, 2018 - ieeexplore.ieee.org
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 …

On the age of information in status update systems with packet management

M Costa, M Codreanu… - IEEE Transactions on …, 2016 - ieeexplore.ieee.org
We consider a communication system in which status updates arrive at a source node, and
should be transmitted through a network to the intended destination node. The status …

Real-time status: How often should one update?

S Kaul, R Yates, M Gruteser - 2012 Proceedings IEEE …, 2012 - ieeexplore.ieee.org
Increasingly ubiquitous communication networks and connectivity via portable devices have
engendered a host of applications in which sources, for example people and environmental …

Optimizing age-of-information in a multi-class queueing system

L Huang, E Modiano - 2015 IEEE international symposium on …, 2015 - ieeexplore.ieee.org
We consider the age-of-information in a multi-class M/G/1 queueing system, where each
class generates packets containing status information. Age of information is a relatively new …

Anytime, anywhere network connectivity, together with portable sensing and computing
devices have led to applications in which sources, for example people or environmental …

Age of information in random access channels

X Chen, K Gatsis, H Hassani… - IEEE Transactions on …, 2022 - ieeexplore.ieee.org
In applications of remote sensing, estimation, and control, timely communication is critical
but not always ensured by high-rate communication. This work proposes decentralized age …

Modern random access: An age of information perspective on irregular repetition slotted ALOHA

A Munari - IEEE Transactions on Communications, 2021 - ieeexplore.ieee.org
Age of information (AoI) is gaining attention as a valuable performance metric for many IoT
systems, in which a large number of devices report time-stamped updates to a central …
