Study Notes
Overview of IoT
- IoT refers to the interconnection of devices, machinery, and tools to the internet via wireless technologies.
- Currently, over 9 billion devices are connected to the internet, projected to exceed 20 billion soon.
- Integrates various technologies: low-power embedded systems, cloud computing, big data, machine learning, and networking.
Terminology and Origin
- The concept emerged in the 2000s, highlighting a shift where devices outnumber human users in internet activity.
- Early discussions included machine-to-machine (M2M) connectivity that could extend to household items.
- Key enablers for IoT identified include RFID, nanotechnology, sensors, and smart networks.
Alternate Definition
- Defined as a network of physical objects embedding technology to interact with their environment or internal states.
Characteristics of IoT
- Efficient and scalable architecture.
- Clear naming and addressing system.
- High presence of dormant nodes; includes mobile and non-IP devices.
- Notable intermittent connectivity of devices.
IoT Market Applications
- Business: Real-time supply chain analytics and robotic machinery.
- Healthcare: Portable health monitoring and electronic recordkeeping.
- Retail: Inventory tracking and smartphone-enabled purchasing.
- Security: Use of biometric locks and remote sensors.
Evolution of Connected Devices
- ATMs became internet-enabled in 1974.
- The World Wide Web revolutionized interactions in 1991.
- Smart meters were introduced in the early 2000s for remote communication.
