A Reference Architecture for IoT
76 likes41,493 views
The document presents an overview of Internet of Things (IoT) concepts and proposes a reference architecture for IoT. It discusses core IoT concerns like connectivity, device management, data handling and security. It describes common IoT device types like Arduino, Raspberry Pi and communication protocols like HTTP, MQTT, CoAP. The proposed reference architecture aims to provide a scalable and secure way to interact with billions of connected devices by addressing issues like management, data processing and disaster recovery. An example implementation of the architecture for an RFID attendance tracking system is also presented.

- 10. History of IoT ๏ The term was coined in 1999 by Kevin Ashton from MIT ๏ Concept has been discussed since 1991 ๏ “What if the Internet was allowed to go beyond connecGng desktops and laptops and could somehow be Ged to the devices around us?”
