Abstract: This tutorial aims to present the current research efforts on the analysis, optimization, and applications of the age of information (AoI) metric, a recently introduced notion that quantifies information freshness in networked and data systems. We will provide comprehensive coverage of the AoI, including its definition, applications, queueing theory based AoI analysis, spatiotemporal models for assessing AoI in large-scale wireless networks, and economic designs (including pricing and mechanism design) for AoI-oriented fresh data markets. Furthermore, we generalize AoI to other age-related semantic metrics and applications. We will also discuss and provide future research directions.
