1.1. Definition and Initial Idea
The concept of the Internet of Things (IoT) was first introduced in the early 1990s by Kevin Ashton, a researcher from MIT. Ashton used the term “Internet of Things” to describe a network of devices that could communicate and share data over the internet. This idea was rooted in the vision of a world where everyday devices could connect and interact with each other without direct human intervention.
1.2. Emergence of the Concept in the 90s
During this period, existing technology was not advanced enough to fully realize the IoT vision. However, some early steps like the development of RFID (Radio Frequency Identification) laid important groundwork. RFID allowed devices to communicate and identify objects without physical contact, an early step toward the realization of IoT.

2.1. Advances in Sensor Technology and Connectivity
Over time, sensor technology and connectivity have advanced rapidly. Small sensors have become more affordable and efficient, allowing devices to collect more accurate data. Networking technologies such as Wi-Fi, Bluetooth, and cellular networks have become faster and more reliable, supporting better communication between devices.
2.2. Emergence of IoT Platforms and Protocols
In the early 2000s, several important platforms and protocols began to emerge. Protocols like MQTT (Message Queuing Telemetry Transport) and CoAP (Constrained Application Protocol) were specifically designed for IoT device communication, addressing challenges like limited bandwidth and high latency. These platforms provided crucial infrastructure for developing more complex IoT applications.
