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 …

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 …

We study a general setting of gossip networks in which a source node forwards its
measurements (in the form of status updates) about some observed physical process to a …

This paper considers a multi-source updating system in which a transmitter node powered
by energy harvesting (EH) sends status updates about multiple sources of information to a …

We consider a network consisting of a single source and receiver nodes that are grouped
into equal-sized clusters. Each cluster corresponds to a distinct community such that nodes …

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 …

This article considers an unmanned aerial vehicles (UAVs) communication network, where
UAV operate as an aerial mobile relay between a source and a destination of the network …

We consider a status update system where multiple sensors communicate timely information
about various random processes to a sink. The sensors share orthogonal sub-channels to …

This article focuses on the service freshness guarantee for cooperative sensing in the
Internet of Everything. Specifically, the peak Age of Information (AoI) is first introduced to …

We consider a status update system consisting of two independent sources and one server
in which packets of each source are generated according to the Poisson process and …
