What is Internet of thingsInternet of Things can be realized in three paradigms:

Internet-oriented (middleware)

Things oriented (sensors)

Semantic-oriented (knowledge)

Definition:

Interconnection of devices, sensors and actuators sharing information and data across platforms through a unified framework and enabling innovative business applications. This is achieved by large scale sensing, analytics and representation using cloud computing and real time streaming analysis

Primary Goal:

To create situation awareness, to make intelligent decisions and to respond to dynamics of the environment
