In multi-source status update systems, sources need to be scheduled appropriately to
maintain timely communication between each of the sources and the monitor. A cyclic …

We consider a status update system consisting of a sampler, a controller, a processing unit,
a transmitter, and a sink. The sampler generates a sample upon receiving a request from the …

This paper investigates a multiuser scheduling problem within an uplink multiple-input multi-
output (MIMO) status update network, consisting of a multi-antenna access point (AP) and …

This article focuses on random access in uplink systems under deadline-constrained
periodic traffic, which is typical for many real-time Internet of Things scenarios. To achieve …

This paper investigates a multiuser scheduling problem within an uplink multiple-input multi-
output (MIMO) status update network, consisting of a multi-antenna base station (BS) and …

We study status updating under inexact knowledge about the battery levels of the energy
harvesting sensors in an IoT network, where users make on-demand requests to a cache …

Unmanned aerial vehicles (UAVs) are increasingly employed in various sensing
applications, highlighting the need for efficient communication systems. Age of Information …

This paper considers the packet scheduling for minimizing the age of information (AoI) in
multi-user networks under delayed feedback, and investigates the impact of feedback delay …

This paper investigates user scheduling in a slotted downlink multi-user multiple-input multi-
output (MU-MIMO) system, where a base station (BS) equipped with multiple antennas …

Abstract Information freshness is crucial for time-critical IoT applications, eg, environment
monitoring and control systems. We consider an Internet of things (IoT) network with multiple …
