Ambient intelligence (AmI) represents the future vision of intelligent computing that can bring
intelligence to our daily life through various domains. In such applications, AmI is often …

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 …

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 …

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 …

In this paper, we study how to optimally manage the freshness of information updates sent
from a source node to a destination via a channel. A proper metric for data freshness at the …

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 …

We consider a communication system in which status updates arrive at a source node, and
should be transmitted through a network to the intended destination node. The status …

In this paper, we consider a scenario where an energy harvesting sensor continuously
monitors a system and sends time-stamped status updates to a destination. The destination …

Motivated by the need to ensure timely delivery of information (eg, status updates) in the
Internet-of-Things (IoT) paradigm, this paper investigates the role of an unmanned aerial …
