From the reviews: "This book, part of the 'Springer Briefs in Computer Science' series, provides the appropriate environment for describing, in a concise manner, forward-thinking solutions for technologies under development. ... this book offers a well-thought-out and nicely deployed set of ideas and solutions on a hot topic. It presents sufficient analysis, which provides a companion for system developers, network designers, academics, and the research community in general. This well-structured reference work contains a wealth of useful material." (Harry Skianis, Computing Reviews, March, 2014)
