Age of information: A new concept, metric, and tool
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 …

Optimal status update for age of information minimization with an energy harvesting source
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 …
