Abstract:
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
shown to be a fundamentally novel metric of timeliness,
significantly different, to existing ones such as delay and
latency. The importance of such a tool is paramount, especially
in contexts other than transport of information, since
communication takes place also to control, or to compute,
or to infer, and not just to reproduce messages of a source.
This volume comes to present and discuss the first body of
works on AoI and discuss future directions that could yield
more challenging and interesting research.
