'With the inception of 5G and its projected use in various real-time applications there has been an increased interest in the low-latency performance of wireless systems. … During the last decade the notion of Age of Information (AoI), information freshness, and its derivatives have sparked interest into analysis and design of communication systems with general timing requirements. This book provides a timely and fresh view on the area of AoI, featuring a highly competent Editorial team and excellent contributions from well-established researchers. Various important aspects are covered, ranging from analytical treatment and stochastic models for AoI, scheduling and transmission policies, interplay with machine learning techniques, as well as the very recent aspects of data economics and valuation. Beyond 5G and towards 6G systems, the relevance of timing performance in wireless communication … will only continue to grow, rendering this book into a valuable and reliable reference for researchers and engineers.'
