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 …
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 …
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 …
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 …
Increasingly ubiquitous communication networks and connectivity via portable devices have engendered a host of applications in which sources, for example people and environmental …
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 …
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 …
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 …
