Study Notes
History of IoT
- The concept of the Internet of Things (IoT) originated in 1945 when Norman Joseph Woodland invented the barcode.
- Notably, the first patent for Radio Frequency Identification (RFID) technology was granted to Mario Cardo in 1980.
- The first practical implementation of RFID technology is attributed to Kevin Ashton in the 1990s, while working at Procter & Gamble.
- Ashton's work with RFID tracking of inventory is why he is widely considered the "father of IoT."
M2M (Machine-to-Machine) IoT Architecture
-
This architecture features three layers: Application, Service, and Network.
Application Layer
- Facilitates communication for various applications such as smart energy, automotive, home, healthcare, and energy.
Service Layer
- Provides application support services like communication, risk management, and application management.
Network Layer
- Enables communication between services and applications using network technologies like Zigbee, Bluetooth, Wi-Fi, and CoAP.
Simplified IoT Architecture
-
This architecture consists of four interconnected layers: Sensing, Network, Application Support, and Application.
Sensing Layer (Device Layer)
- Includes devices like sensors, actuators, RFID tags, human entities, and other data sources.
- The layer collects and gathers data from various sources.
Network Layer
- Utilizes IoT gateways to enable communication between different layers.
- It connects local services, data, and peer systems through the network.
Application Support Layer
- Houses software components like operating systems, application support systems, and resource management systems.
- Performs crucial tasks such as data capture, information extraction, data analytics, and data privacy management.
Application Layer
- The highest level of abstraction in the architecture.
- Integrates with smart applications, processes real-time data, and connects the physical world with the digital world.
Building Blocks of IoT
-
Core components of an IoT system include:
-
Devices/Nodes/Sensors/Hardware: Essential for data collection and sensing.
-
Gateways/Local Processing Nodes: Support networking and data processing.
-
Communication/Connectivity: Enables data transmission through various means like Wi-Fi, Bluetooth, or Cloud.
-
Software: Includes operating systems, protocols (e.g., CoAP, Zigbee), APIs, and embedded software.
-
Cloud: Provides storage, processing, and management of data collected from IoT systems.
