The next wave of wireless technologies is proliferating in connecting things among
themselves as well as to humans. In the era of the Internet of Things (IoT), billions of …

As one of the key communication scenarios in the fifth-generation and also the sixth-
generation (6G) mobile communication networks, ultrareliable and low-latency …

We summarize recent contributions in the broad area of age of information (AoI). In
particular, we describe the current state of the art in the design and optimization of low …

Internet of Things (IoT) generates large amounts of data at the network edge. Machine
learning models are often built on these data, to enable the detection, classification, and …

Age of information (AoI) was introduced in the early 2010s as a notion to characterize the
freshness of the knowledge a system has about a process observed remotely. AoI was …

In this paper, we consider a wireless broadcast network with a base station sending time-
sensitive information to a number of clients through unreliable channels. The Age of …

Information usually has the highest value when it is fresh. For example, real-time knowledge
about the location, orientation, and speed of motor vehicles is imperative in autonomous …

Due to the advantages of flexible deployment and extensive coverage, unmanned aerial
vehicles (UAVs) have significant potential for sensing applications in the next generation of …

We examine multiple independent sources providing status updates to a monitor through
simple queues. We formulate an age of information (AoI) timeliness metric and derive a …

In this work, we study the UAV-enabled data collection problem for high information
freshness in wireless sensor networks, where one UAV is dispatched to collect information …
