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 …

In this paper, we study a real-time monitoring system in which multiple source nodes are
responsible for sending update packets to a common destination node in order to maintain …

We consider a system consisting of N source nodes communicating with a common receiver.
Each source node has a buffer of infinite capacity to store incoming bursty traffic in the form …

This article comprehensively surveys the area of age of information (AoI) in the wireless
networks and focuses on categorising and reviewing the current progress on AoI from an …

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 …

This paper studies the interplay between device-to-device (D2D) communications and real-
time monitoring systems in a cellular-based Internet of Things (IoT) network. In particular …

In this work, we consider a real-time IoT monitoring system in which an energy harvesting
sensor with a finite-size battery measures a physical process and transmits the status …

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 …

In this work, we derive optimal transmission policies for an energy harvesting status update
system. The system monitors a stochastic process which can be in one of two states of …

A status updating system is considered in which data from multiple sources are sampled by
an energy harvesting sensor and transmitted to a remote destination through an erasure …
