The Internet of Things (IoT) is an emerging technology with an expected 50 billion connected devices by 2020. Key components include hardware (sensors), middleware for storage, and technologies like RFID and wireless sensor networks, which facilitate low-cost and efficient communication. IoT applications span personal, home, enterprise, and utility domains, with unique identification enabled by IPv6.

5. TECHNOLOGIES

6. RFID
•It help in the automatic identification of anything they are attached to
acting as an electronic barcode

7. WIRELESS SENSOR NETWORK
 Wireless communications are efficient, low cost.
 The Low power miniature devices are used in
remote sensing applications.
 WSNs are substantial and multidisciplinary in
nature.
 The components of WSN monitoring network:
Hardware
Communication Stack
Middleware
Secure Data Aggregation

8. ADDRESSING SCHEMES IPV6
 Every element that is already connected must be
identified by their unique identification.
 IPv6 also gives a very good option to access the
resources uniquely and remotely.
 IPv6 will enable addressing home appliances
uniquely.

9. APPLICATIONS
 The applications are categorized into four
application domains:

10. PERSONAL & HOME

11. ENTERPRISE

12. UTILITIES

13. MOBILE
