Optimizing Age-of-Information in a Multi-class Queueing System [PDF]
, 2015 We consider the age-of-information in a multi-class $M/G/1$ queueing system, where each class generates packets containing status information. Age of information is a relatively new metric that measures the amount of time that elapsed between status ...

Age Optimal Information Gathering and Dissemination on Graphs
, 2019 We consider the problem of timely exchange of updates between a central station and a set of ground terminals $V$, via a mobile agent that traverses across the ground terminals along a mobility graph $G = (V, E)$.

Using Timeliness in Tracking Infections
Entropy, 2022 We consider real-time timely tracking of infection status (e.g., COVID-19) of individuals in a population. In this work, a health care provider wants to detect both infected people and people who have recovered from the disease as quickly as possible. In

On the Potential of Enhancing Delay-Tolerant Routing Protocols via Age of Information
Future Internet, 2022 In this paper, we study the potential of using the metric of Age of Information (AoI) for enhancing delay-tolerant routing protocols. The latter have been proposed for alleviating the impact of long roundtrip time in networks operating in harsh ...
