We study status updating under two-way delay in a system consisting of a sampler, a sink,
and a controller residing at the sink. The controller drives the sampling process by sending …

The age of information (AoI) metric was proposed to measure the freshness of messages
obtained at the terminal node of a status updating system. In this paper, the AoI of a discrete …

In this paper, for discrete time status updating system with infinite size, we derive the explicit
expression of average age of information (AoI) and its stationary distribution. Notice that …

In practical status updating systems, most decisions made at monitors are based on diverse
data streams. Due to the cask effect, it can be cognised that the effectiveness of decisions is …

The continuous development of modern communication and computation gives rise to a
large number of applications based on Internet of Things (IoT) technology. Considering the …

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 work studies the information freshness of the vehicle-to-infrastructure status updating in
Internet of vehicles, which is modeled as a multi-source Ber/Geo/1/1 preemptive queueing …
