Article body

An Auburn engineering assistant professor is the co-author of a new monograph revealing the Age of Information, or AoI, concept and its connections with information theory, signal processing and control theory.

Yin Sun, an electrical and computer engineering assistant professor, collaborated with a research group from the Massachusetts Institute of Technology to produce the book, "Age of Information: A New Metric for Information Freshness." It details the analytical tools and insightful results on the generation of information-update packets and the design of network protocols when forwarding the packets to their destinations.

The book is centered around AoI, which provides a means of quantifying the freshness of information and an opportunity to improve the performance of real-time systems and networks. As research on AoI has progressed, it has become apparent that well-known design principles and traditional data networks must be re-examined for an enhanced, optimal information freshness in emerging real-time applications.
