Cyber Physical Systems are systems of collaborating computational elements controlling physical entities. The CPS is expected to be the breakthrough for the next generation that uses computing, communication and control to make intelligent and autonomous systems. This book provides state-of-the-art research results and trends related to CPS, including system architecture, development, modeling & simulation, security, privacy, trust and energy efficiency. Such knowledge is required not only for researchers and practitioners, but also for policy makers, system managers, owners and administrators.
