Five Clark School authors part of new 'Age of Information' book

A comprehensive new book on the “Age of Information” network performance metric features chapters by three ECE/ISR faculty and two of their recent alumni.

Age of Information: Foundations and Applications is being published by Cambridge University Press in February 2023. The text provides detailed information on Age of Information (AoI), a metric ushering in new opportunities for rethinking communication system design. It gives the reader a solid background in AoI’s communication and network theoretic foundations, discusses AoI’s implications for signal processing and control theory, and covers the important potential of recent research.

The book includes examples of the extensive real-world applications of this vital metric, including caching, the Internet of Things, and energy harvesting networks. The far-reaching applications of AoI include networked monitoring systems, cyber-physical systems, and information-oriented systems and data analytics applications ranging from the stock market to social networks. The future role of AoI in 5G communication systems and beyond will make the book a vital resource for graduate students, researchers and professionals.

Chapter 6, “Age of Information in Source Coding,” is written by ECE Department Chair and Professor Sennur Ulukus (ECE/ISR) and two of her former advisees, Baturalp Buyukates (ECE PhD 2021), currently a postdoctoral researcher at the University of Southern California; and Melih Bastopcu (ECE PhD 2021), currently a postdoctoral researcher at the University of Illinois, Urbana-Champaign.

Chapter 9, “AoI-driven transmission scheduling in wireless networks,” is written by Distinguished University Professor Emeritus Anthony Ephremides (ECE/ISR); Qing He and György Dán, KTH Royal Institute of Technology, Sweden; and Di Yuan, Uppsala University, Sweden.

Chapter 11, “Networked control subject to random processing delay,” is written by Distinguished University Professor John Baras (ECE/ISR); and Touraj Soleymani and Karl Henrik Johansson, KTH Royal Institute of Technology, Sweden.

Age of Information: Foundations and Applications is edited by Nikolaos Pappas, Linköpings Universitet, Sweden; and Mohamed A. Abd-Elmagid, Bo Zhou, Walid Saad, and Harpreet S. Dhillon, of Virginia Tech.
