Internet of 
Things 
(IoT)
What is IoT? 
(1) The Internet of Things, also called The Internet of 
Objects, refers to a wireless network between objects, 
usually the network will be wireless and self-configuring, 
such as household appliances. 
------Wikipedia 
(2) By embedding short-range mobile transceivers into a 
wide array of additional gadgets and everyday items, 
enabling new forms of communication between people 
and things, and between things themselves. 
------WSIS 2005

Why IoT 
• The Internet of Things (IoT) is the next evolution 
of the Internet where devices of all types and 
capabilities are Internet accessible. IP-based Web 
Services will be the driving force behind the 
global growth and demand for the IoT.
