Study Notes
History of IoT
- The history of IoT can be traced back to 1945 with the invention of the barcode by Norman Joseph Woodland.
- The concept of IoT was first introduced in 1973 with the development of RFID (Radio Frequency Identification) technology.
- The first RFID patent was granted to Mario Cardo in 1980.
- In the 1990s, Kevin Ashton, while working for Procter & Gamble, pioneered the practical use of RFID technology for inventory tracking, establishing him as the "father of IoT".
- 2004 onwards, the potential of IoT has been extensively researched and explored, with continuous development of the technology and its applications ongoing.
M2M IoT Architecture
- M2M (Machine-to-Machine) IoT architecture consists of three main layers:
- Application Layer: Enables user interaction and application execution, facilitating communication between applications and APIs. Examples include smart energy, automotive, home, healthcare, and energy applications.
- Service Layer: Holds application support services, including communication, risk management, and application management services.
- Network Layer: Facilitates communication between services and applications through various network technologies like Zigbee, Bluetooth, Wi-Fi, and CoAP.
Simplified IoT Architecture
- The simplified IoT architecture, commonly used today, comprises four layers:
- Sensing Layer (Device Layer): Consists of devices, sensors, actuators, RFID tags, personal entities, and humans, responsible for collecting data from various locations.
- Network Layer: Connects different layers using IoT gateways and local services, enabling communication between data, peer systems, and the application layer.
- Application Support Layer (Service Layer): Provides operational and management support for applications, encompassing software like operating systems, application service systems, resource management systems, and data interchange systems.
- Application Layer: Represents the user interactions with IoT applications, processing real-time data and connecting the physical and digital realms.
Building Blocks of IoT
- Key building blocks of IoT include:
- Devices (End Devices/Nodes): Sensors and hardware, crucial components for data collection.
- Gateways (Local Processing Nodes): Enable networking and facilitate data processing and communication.
- Communication: Connectivity options like Wi-Fi, Bluetooth, and cloud platforms, facilitating data exchange.
- Software: Operating systems, embedded operating systems, various protocols (CoAP, Zigbee), software APIs used in IoT systems.
- Cloud: Data storage systems, essential for storing and managing data collected from IoT devices.
