Age of Information in Practice
, 2021 While age of Information (AoI) has gained importance as a metric characterizing the fresh-ness of information in information-update systems and time-critical applications, most previous studies on AoI have been theoretical. In this chapter, we compile a set of recent works reporting API measurements in real-life networks and experimental testbeds, and ...

Age-of-Information Minimization in Healthcare IoT Using Distributionally Robust Optimization
IEEE Internet of Things Journal, 2022 In this article, we consider a cellular-based healthcare Internet of Things (IoT) system with imperfect channel state information (CSI), where a healthcare IoT device first receives radio frequency (RF) energy from the small cell base station (SBS) and ...

On the Age of Information in Status Update Systems With Packet Management [PDF]
IEEE Transactions on Information Theory, 2015 We consider a communication system in which status updates arrive at a source node, and should be transmitted through a network to the intended destination node. The status updates are samples of a random process under observation, transmitted as packets,
