Keeping sensor data fresh is desired for Industrial Internet of Things (IIoT), especially, in real-
time monitoring applications. However, this may require sensors always in active mode and …

Ensuring data freshness is important for Industrial Internet of Things (IIoT). In this article, we
consider a typical IIoT application where multiple sensors monitor some time-varying …

We consider the uplink of an energy harvesting (EH) wireless sensor network (WSN) where
N single-antenna sensors communicate with a common fusion center (FC) with the aim of …

The proliferation of Internet of Things (IoT) applications has prompted the continuous
increase of research efforts in recent years. In light of the diversified use cases and service …

Timely information updates are critical for real-time monitoring and control applications in
the Internet of Things (IoT). In this paper, we consider a multi-antenna cellular IoT for state …

The focus of this work is on minimizing the time average of the weighted sum of the Age-of-
Information in a multi-sensor system in the setting where all sensors report their …
