In a typical Internet of Things (IoT) application where a central controller collects status
updates from multiple terminals, eg, sensors and monitors, through a wireless multiaccess …

We study the problem of minimizing the time-average expected Age of Information for status
updates sent by an energy-harvesting source with a finite-capacity battery. In prior literature …

Information freshness in IoT-based status update systems has recently been studied through
the Age of Information (AoI) and Peak AoI (PAoI) performance metrics. In this article, we …

We consider a system of multiple sources generating status update packets, which need to
be sent by a single transmitter to a destination over a network. In the model we study, the …

This paper investigates the age of information in a single-source status update system with
energy constraints. Specifically, a source provides status updates to a destination through a …

In the upcoming 5G and beyond systems, ultra-reliable and low latency communication
(URLLC) has been considered as the key enabler to support diverse mission-critical …

The freshness of status information is of great importance for time-critical Internet-of-Things
(IoT) applications. A metric measuring status freshness is the Age of Information (AoI), which …

Unmanned aerial vehicle (UAV) crowdsensing (UCS) is an emerging data collection
paradigm to provide reliable and high quality urban sensing services, with age-of …

In this paper, we investigate the timeliness performance of a downlink wireless
communication system with non-orthogonal multiple access (NOMA). The timeliness of the …

Age of Information (AoI), measures the time elapsed since the last received information
packet was generated at the source. We consider the problem of AoI minimization for single …
