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.
Digital locks enable remote access control via smartphones.
Smart healthcare devices can alert for emergencies.
Smart vehicles self-diagnose system failures.
Smart cities feature interconnected infrastructure for optimal operations.
