Age of Information: Control and Estimation

Abstract

The purpose of this work is to study the impact of the timeliness of information exchange on application performance, by developing a deeper analytical understanding of the AoI metric over a varied set of network instantiations. We developed new tools for the estimation and reconstruction of the real-time process being observed from across a network, and studied the impact of timeliness of information exchange on the optimal reconstruction process in a novel way using the AoI metric. Additionally, our study also included information freshness for multiple competing sources and multiple transmission hops.
