Internet of Things (IoT) can be defined as a dynamic global network infrastructure with self configuring capabilities based on standard and communication protocols where physical and virtual things are seamlessly integrated into an auto-organized network with independent and cooperative service and applications. Things (or objects) in IoT are expected to become active participants in information processes by exchanging data and information ‘sensed’ about the environment. IoT will not only play a key role in the next generation of information, network, and communication developing, but also brings promising opportunities and challenges. For example, to build a real cyber physical system will face numerous challenges because there exist a lot of differences between the cyber system and the physical system.
