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 …

[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 …

A reinforcement learning framework for optimizing age of information in RF-powered communication systems

MA Abd-Elmagid, HS Dhillon… - IEEE Transactions on …, 2020 - ieeexplore.ieee.org

Timely communication in federated learning

B Buyukates, S Ulukus - IEEE INFOCOM 2021-IEEE …, 2021 - ieeexplore.ieee.org
We consider a federated learning framework in which a parameter server (PS) trains a
global model by using n clients without actually storing the client data centrally at a cloud …

Minimizing the age of information in wireless networks with stochastic arrivals

I Kadota, E Modiano - Proceedings of the Twentieth ACM International …, 2019 - dl.acm.org
We consider a wireless network with a base station serving multiple traffic streams to
different destinations. Packets from each stream arrive to the base station according to a …

A reinforcement learning approach to age of information in multi-user networks with HARQ

ET Ceran, D Gündüz, A György - IEEE Journal on Selected …, 2021 - ieeexplore.ieee.org
Scheduling the transmission of time-sensitive information from a source node to multiple
users over error-prone communication channels is studied with the goal of minimizing the …

Information freshness in cache updating systems

M Bastopcu, S Ulukus - IEEE Transactions on Wireless …, 2020 - ieeexplore.ieee.org
We consider a cache updating system with a source, a cache and a user. There are n files.
The source keeps the freshest version of the files which are updated with known rates λ i …

Minimum age of information in the Internet of Things with non-uniform status packet sizes

B Zhou, W Saad - IEEE Transactions on Wireless …, 2019 - ieeexplore.ieee.org
In this paper, a real-time Internet of Things (IoT) monitoring system is considered in which
the IoT devices are scheduled to sample associated underlying physical processes and …

Caching transient content for IoT sensing: Multi-agent soft actor-critic

X Wu, X Li, J Li, PC Ching, VCM Leung… - IEEE Transactions on …, 2021 - ieeexplore.ieee.org
Edge nodes (ENs) in Internet of Things commonly serve as gateways to cache sensing data
while providing accessing services for data consumers. This paper considers multiple ENs …

Who should Google Scholar update more often?

M Bastopcu, S Ulukus - IEEE INFOCOM 2020-IEEE Conference …, 2020 - ieeexplore.ieee.org
We consider a resource-constrained updater, such as Google Scholar, which wishes to
update the citation records of a group of researchers, who have different mean citation rates …
