Iot architecture

This IOT architecture describes about how things get connected via internet.In short, the Internet of Things refers to the rapidly growing network of connected objects that are able to collect and exchange data using embedded sensors. Thermostats, cars, lights, refrigerators, and more appliances can all be connected to the IoT.In short, the Internet of Things refers to the rapidly growing network of connected objects that are able to collect and exchange data using embedded sensors.

3. INTRODUCTION 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. 3

4. History of IoT The concept of the Internet of Things first became popular in 1999 invented by kevin Ashton , through the Auto-ID Center at MIT and related market-analysis publications. Radio-frequency identification ( RFID) was seen as a prerequisite for the IoT at that point . 4

5. The Structure of IoT Th e I oT ca n b e vie w ed a s a gigantic net w o r k c o nsist i n g of ne t w o r ks o f devi c es a n d c ompu t ers connected through a series of intermediate technologies where numerous technologies like RFIDs, wireless connections may act as enablers of this connectivity. Tagging Things : Real-time item traceability and addressability by RFID s. Feeling Things : Sensors act as primary devices to collect data from the environment. Shrinking Things : M iniaturization and Nanotechnology has provoked the ability of smaller things to interact and connect within the “things” or “smart devices.” 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. 5

6. LAYERED ARCHITECTURE OF IOT 6

7. DEVICE LAYER Provides a user interface for using IoT . Different applications for various sectors like Transportation, Healthcare, Agriculture, Supply chains, Government, Retail etc. Devices and sensors used are: GPS Gyroscope Accelerometer Wifi Ethernet Bluetooth 7

8. NETWORK LAYER Robust and High performance network infrastructure Supports the communication requirements for latency, bandwidth or security Allows multiple organizations to share and use the same network independently Encryption,signal processing,LTE,Wifi,Sim Module,GSM,Micro controller,Embedded-os etc …are used in network layer. 8

9. SERVICE LAYER Also termed as Application service Layer. Capturing of periodic sensory data . Data Analytics (Extracts relevant information from massive amount of raw data ). Streaming Analytics (Process real time data ). Ensures security and privacy of data. 9

10. Lowest Abstraction Layer. With sensors we are creating digital nervous system. Incorporated to measure physical quantities. Interconnects the physical and digital world. Collects and process the real time information. Transportation,Health care,Tracing people,Climatic conditions.etc comes under application layer. APPLICATION LAYER 10

15. Sensors even in the cow! In the world of IoT, even the cows will be connected and monitored. Sensors are implanted in the ears of cattle. This allows farmers to monitor cows’ health and track their movements, ensuring a healthier, more plentiful supply of milk and meat for people to consume. On average, each cow generates about 200 MB of information per year. 15

16. Security in IoT  Software can be hackable.  Connection is exposed.  it is vulnerable, exposed, can be tapped.  Weapons of mass disruption. 16
