IOT and Characteristics of IOT
- 3. What's Internet of Things ? The Internet of Things (I.O.T.) 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. I.O.T. is an ecosystem of connected physical objects that are accessible through Internet. I.O.T. 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.
- 4. “ Things, " in the I.O.T. 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 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.

- 6. How All this actually happens..
- 7. Characteristics of I.O.T. :- Connectivity : Things in I.O.T. should be connected to the infrastructure, without connection nothing makes sense. Intelligence : Extraction of knowledge from the generated data is important, sensor generate data and this data and this data should be interpreted properly. Scalability : The no. of things getting connected to the I.O.T. infrastructure is increased day by day. Hence, an IOT setup shall be able to handle the massive expansion.
- 8. CISCO'S PREVISION In 2008 the number of things connected to the Internet was greater than the people living on Earth. Within 2020 the number of things connected to the Internet will be about 50 billion.
- 9. Unique Identity : Each IOT device has an I.P. address. This identity is helpful in tracking the equipment and at times to query its status. Dynamic and Self-Adapting : The IOT device must dynamically adopt itself to the changing context. Assume a camera meant for surveillance, it may have to work in different conditions and at different light situations ( morning, afternoon, night ). Architecture : Architecture cannot be homogeneous in nature, it should be heterogeneous in nature supporting different manufacturer product to be in an IOT network.
- 10. Safety : Having got all the things connected with the Internet possess a major threat, as our personal data is also there and it can be tampered with, if proper safety measures are not taken.
