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

Rejuvenation and the Age of Information [PDF]
2019 IEEE International Symposium on Software Reliability Engineering Workshops (ISSREW), 2019 Two decades after the seminal paper on software aging and rejuvenation appeared in 1995, a new concept and metric referred to as the age of information (AoI) has been gaining attention from practitioners and the research community. In this vision paper, our aim is to show the similarities and differences between software aging and information aging. 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 ...
