Age of Information (AoI) is an emerging concept to model information freshness from the
perspective of destinations of information deliveries. Serving as a metric to characterize the …

We consider a wireless network with a base station serving multiple traffic streams to
different destinations. Packets from each stream arrive to the base station according to a …

The boom in Internet of Things has spawned many real-time applications, which have
stringent requirements for the timeliness of information delivery. As a result, age of …

Age of Information (AoI) is a well-investigated timeliness metric for data collected from
sensors. Various packet scheduling policies have been proposed in order to optimize AoI. It …

The rapid development of real-time applications such as the Internet of Things (IoT) puts
forward high requirements for the data freshness of wireless networks. The metric Age of …

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 …

In this article, we provide an accessible introduction to the emerging idea of Age of
Information (AoI) that quantifies freshness of information and explore its possible role in the …
