Understanding age of information in large-scale wireless networks

HH Yang, C Xu, X Wang, D Feng… - IEEE Transactions on …, 2021 - ieeexplore.ieee.org
The notion of age-of-information (AoI) is investigated in the context of large-scale wireless
networks, in which transmitters need to send a sequence of information packets, which are …

Discrete-time queueing model of age of information with multiple information sources

N Akar, O Dogan - IEEE Internet of Things Journal, 2021 - ieeexplore.ieee.org
Information freshness in IoT-based status update systems has recently been studied through
the Age of Information (AoI) and Peak AoI (PAoI) performance metrics. In this article, we …

Age of processing: Age-driven status sampling and processing offloading for edge-computing-enabled real-time IoT applications

R Li, Q Ma, J Gong, Z Zhou… - IEEE Internet of Things …, 2021 - ieeexplore.ieee.org
The freshness of status information is of great importance for time-critical Internet-of-Things
(IoT) applications. A metric measuring status freshness is the Age of Information (AoI), which …

The age of information in a discrete time queue: Stationary distribution and non-linear age mean analysis

A Kosta, N Pappas, A Ephremides… - IEEE Journal on …, 2021 - ieeexplore.ieee.org
In this work, we investigate information freshness in a status update communication system

The Age of Information in Wireless Cellular Systems: Gaps, Open Problems, and Research Challenges

E Zhbankova, A Khakimov, E Markova, Y Gaidamaka - Sensors, 2023 - mdpi.com
One of the critical use cases for prospective fifth generation (5G) cellular systems is the
delivery of the state of the remote systems to the control center. Such services are relevant …

Age of information in multihop multicast networks

B Buyukates, A Soysal, S Ulukus - Journal of Communications …, 2019 - ieeexplore.ieee.org
We consider the age of information in a multihop multicast network where there is a single
source node sending timesensitive updates to n L end nodes, and L denotes the number of …

Closed-form characterization of the MGF of AoI in energy harvesting status update systems

MA Abd-Elmagid, HS Dhillon - IEEE Transactions on …, 2022 - ieeexplore.ieee.org
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 …

Age-delay tradeoffs in queueing systems

R Talak, EH Modiano - IEEE Transactions on Information …, 2020 - ieeexplore.ieee.org
We consider an m server system in which each server can service at most one update
packet at a time. The system designer controls (1) scheduling-the order in which the packets …

Timely distributed computation with stragglers

B Buyukates, S Ulukus - IEEE Transactions on …, 2020 - ieeexplore.ieee.org
We consider a status update system in which the update packets need to be processed to
extract the embedded useful information. The source node sends the acquired information to …

Spatiotemporal analysis for age of information in random access networks under last-come first-serve with replacement protocol

HH Yang, A Arafa, TQS Quek… - IEEE Transactions on …, 2021 - ieeexplore.ieee.org
We investigate the age-of-information (AoI) in the context of random access networks, in
which transmitters need to send a sequence of information packets to the intended receivers …
