Book excerpt: This book provides a fresh look at the most recent evolution of mobility management paradigms for next generation networks. It covers the basic principles of mobility management, its underlying technologies and environments, and the reasons for specific architectural design choices. The book serves to de-construct the way that mobility management has been developed up until recently. To that end, it goes beyond more traditional, centralized approaches to the topic, and offers insights into practical ways of distributing mobility management in a way that is more suited for operators, and end-users. It explains such key concepts as mobility management and estimation, showing how and why these aspects should be integrated into future mobility management solutions. The text will be of interest to students, computer network engineers, and researchers involved in innovation and standardization activities focused on the evolution of mobility management aspects.
