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 …

Value of Information (VoI) is a concept to assess the usefulness of information for a specific
goal, and has in the last decade experienced a growing interest also for Wireless Sensor …

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 …

Generative artificial intelligence (GAI) has emerged as a rapidly burgeoning field
demonstrating significant potential in creating diverse content intelligently and automatically …

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 …

We consider a status update communication system consisting of a source-destination link.
A stochastic process is observed at the source, where samples are extracted at random time …

In this paper, a general framework is formalised to characterise the value of information (VoI)
in hidden Markov models. Specifically, the VoI is defined as the mutual information between …

The massive device deployments in the Internet of Things (IoT) generate immense amounts
of data that can be leveraged to improve overall network performance. This paper outlines …

We study the average age of information (AoI) in a system where physical sources produce
independent discrete-time updates that are each observed by several sensors. We devise a …

Age of Information (AoI) has recently become a new performance metric that captures the
freshness/timeliness of information at end users in Internet of Things (IoT). Most existing …
