We analyze a remote sensing system in the Internet of things, where uncoordinated nodes
send status updates to a common receiver to achieve information freshness, quantified …

Sensor data exchanges in IoT applications can experience a variable delay due to changes
in the communication environment and sharing of processing capabilities. This variability …

Consider a scenario where a source continuously monitors an object and sends time-
stamped status updates to a destination through a rate-limited link. In order to measure the …

Remote sensing systems can exploit age of information as a performance metric to track the
freshness of the data exchanged. However, sensing terminals often have a finite time span …

Scheduling updates from remote sensors is a key task for the internet of things (IoT). In this
context, the mathematical concept of age of information is often used to capture the …

Applications like environmental sensing, and health and activity sensing, are supported by
networks of devices (nodes) that send periodic packet transmissions over the wireless …

Low Earth Orbit (LEO) satellite constellations are bringing the Internet of Things (IoT) to the
space arena, also known as non-terrestrial networks. Several IoT satellite applications for …

Applications like environmental sensing, and health and activity sensing, are supported by
networks of devices (nodes) that send periodic packet transmissions over the wireless …

In this paper, we study how to collect fresh data in time-varying networks with power
constrained users. We measure data freshness from the perspective of the central controller …

Sensor sources submit updates to a monitor through an unslotted, uncoordinated, unreliable
multiple access collision channel. The channel is unreliable; a collision-free transmission is …
