Internet of Things (IOT)
What
is Internet of Things?
The Internet of Things(IOT) is the network of physical
objects or "things" embedded with electronics, software, sensors, and
network connectivity, which enables these objects to collect and exchange data.
IoT allows objects to be sensed and controlled remotely across existing network
infrastructure, creating opportunities for more direct integration between the
physical world and computer-based systems, and resulting in improved
efficiency, accuracy and economic benefit
"Things," in
the IoT sense, can refer to a wide variety of devices such as heart monitoring
implants, biochip transponders on farm animals, electric clams in coastal
waters, automobiles with built-in sensors, DNA analysis devices for
environmental/food/pathogen monitoring or field operation devices that assist
fire-fighters in search and rescue operations.
These devices collect useful data with the help of
various existing technologies and then autonomously flow the data between other
devices.
How
IoT Works?
Internet of Things is
not the result of a single novel technology; instead, several complementary
technical developments provide capabilities that taken together help to bridge
the gap between the virtual and physical world.
These capabilities include:
Ø Communication
and cooperation
Ø Addressability
Ø Identification
Ø Sensing
Ø Actuation
Ø Embedded
information processing
Ø Localization
Ø User
interfaces
The Structure of IoT
The IoT can be viewed as a gigantic network consisting of
networks of devices and computers connected through a series of intermediate
technologies where numerous technologies like RFIDs, wireless connections may
act as enablers of this connectivity.
Ø Tagging Things: Real-time item traceability
and addressability by RFIDs.
Ø Feeling Things: Sensors act as primary
devices to collect data from the environment.
Ø Shrinking Things: Miniaturization and
Nanotechnology has provoked the ability of smaller things to interact and
connect within the “things” or “smart devices.”
Ø Thinking Things: Embedded intelligence in
devices through sensors has formed the network connection to the Internet. It
can make the “things” realizing the intelligent control.

Internet of Things is the next stage of the information
revolution and referenced the inter- connectivity of everything from urban
transport to medical devices to household appliances. Integration with the
Internet implies that devices will use an IP address as a unique identifier.
However, due to the limited address space of IPv4 (which allows for 4.3 billion
unique addresses), objects in the IoT will have to use IPv6 to accommodate the
extremely large address space required.
