In recent years, the landscape of computing paradigms has witnessed a gradual yet
remarkable shift from monolithic computing to distributed and decentralized paradigms such …

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 …

This article investigates the unmanned aerial vehicle (UAV)-assisted wireless powered
Internet-of-Things system, where a UAV takes off from a data center, flies to each of the …

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 restless multi-armed bandit problem is a paradigmatic modeling framework for optimal
dynamic priority allocation in stochastic models of wide-ranging applications that has been …

In this paper, we introduce a new performance metric in the framework of status updates that
we will refer to as the Age of Incorrect Information (AoII). This new metric deals with the …

The effective operation of time-critical Internet of things (IoT) applications requires real-time
reporting of fresh status information of underlying physical processes. In this paper, a real …

Age of Information (AoI) is a performance metric that captures the freshness of the
information from the perspective of the destination. The AoI measures the time that elapsed …

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 …

This work is motivated by the need of collecting fresh data from power-constrained sensors
in the industrial Internet of Things (IIoT) network. A recently proposed metric, the Age of …
