Definition and characteristics of IoT:

•  A dynamic global network infrastructure with self – configuring based on standard and interoperable communication protocols where physical and virtual “things” have identified, physical attributes, and virtual personalities and use intelligent interfaces, often communicate data associated with users and their environment
• Characteristics:  IoT devices and systems may have the capability to dynamically adapt with the changing contexts and take actions based on their operating condition.Ex: Surveillance cameras can adapt their modes based on whether it is day or night.
•  Self – Configuring: :IoT devices may have self-Configuring capability allowing a large number of devices to work together to provide certain functionality .
•  Interoperable communication protocols:: IoT Devices may support a number of interoperable communication protocols and can communicate with other devices and also with the infrastructure.
•  Unique Identity::Each IoT devices has a unique identity and a unique identifier.IPaddress, URI).IoT systems may have intelligent interfaces which adapt based on the context, allow communication with users and the environment contexts.
•  Integrated into information network:: IoT devices are usually integrated into the information network that allows them to communicate and exchange data with other devices and systemsDynamic and self-Adapting
