What is IoT? Internet of Things Definition and Meaning (2024 Review)

Exclusive Neuroject Article: The Internet of Things (IoT) refers to the interconnected network of physical objects, often termed “things,” incorporating sensors, software, and various technologies. The primary objective is to facilitate the exchange of data among these devices and systems through internet connectivity. These devices span from commonplace household items to advanced industrial tools. Currently, there are over 7 billion connected IoT devices, and industry experts anticipate a surge to 10 billion by 2020 and a substantial growth to 22 billion by 2025.

In an Internet of Things (IoT) ecosystem, smart devices equipped with embedded systems, including processors, sensors, and communication hardware, play a pivotal role in collecting, transmitting, and responding to data from their surroundings. These IoT devices share the data they gather by connecting to an IoT gateway, functioning as a central hub where information can be sent. Before sharing, the data may undergo analysis on an edge device, allowing local processing to reduce the amount of data transmitted to the cloud, thereby minimizing bandwidth usage.

Inter-device communication is a common practice among these devices, enabling them to exchange information and act upon the received data. The devices are designed to perform most tasks autonomously, requiring minimal human intervention. However, individuals can engage with the devices, such as configuring them, providing instructions, or accessing the data they generate.

The selection of connectivity, networking, and communication protocols for these web-enabled devices is typically contingent on the specific applications of IoT being implemented.

Moreover, it leverages artificial intelligence and machine learning to enhance and streamline data collection processes. This integration of advanced technologies contributes to making data collection more efficient and dynamic within the IoT framework.

 

Historical Context and Evolution

1969: The inception of the Internet of Things is closely tied to the origins of the Internet itself, initially emerging as part of DARPA (Defense Advanced Research Projects Agency) in 1962 and evolving into ARPANET (Advanced Research Projects Agency Network) in 1969.

1980: During the 1980s, commercial service providers began facilitating public access to ARPANET, paving the way for the development of the modern internet. The foundational communication infrastructure for much of it relies on satellites and landlines. The concept of IoT dates back to the late 1980s, originating from the pioneering work of researchers at Carnegie Mellon University.

1991: In 1991, British entrepreneur Kevin Ashton, while at the Auto-ID Center, coined the term “Internet of Things.” Ashton proposed the utilization of radio frequency identification (RFID) and various sensors to facilitate the tracking and monitoring of physical objects, a concept that eventually laid the groundwork for the contemporary IoT.

1993: In 1993, Global Positioning Satellites (GPS) became operational, providing a stable and highly functional system with 24 satellites. This development, coupled with the deployment of privately owned commercial satellites, significantly enhanced the functionality of the Industrial Internet of Things (IIoT).

1999: The formal conceptualization of the Internet of Things did not occur until 1999, although early examples date back to the early 1980s. Notably, a Coca-Cola machine at Carnegie Mellon University served as one of the first instances of its application. Programmers would connect to the internet to check the availability and temperature of drinks in the machine before making a purchase.

Kevin Ashton, Executive Director of MIT’s Auto-ID Labs, officially coined the term “Internet of Things” during a 1999 presentation for Procter & Gamble. He envisioned a future where computers, independent of human input, could gather and manage information about physical objects, thereby reducing waste, loss, and costs.

2000: In the early 2000s, Kevin Ashton advocated for Radio Frequency Identification (RFID) as a crucial element for the IoT, particularly in inventory tracking. This concept gained traction, and by 2002-2003, major organizations like Walmart and the US Department of Defense embraced inventory tracking through RFID and its technologies.

2003: Subsequently, it has undergone rapid expansion. The ZigBee Alliance, formed in 2003, played a pivotal role in advocating for the development and adoption of it. In 2009, the inaugural commercial IoT product, Xively, was introduced. Presently, IoT is integrated across diverse industries, spanning healthcare, manufacturing, retail, and smart homes.

2010: The Industrial Internet of Things emerged around 2010, extending the capabilities of the IoT with smart sensors and actuators integrated into industrial applications. The cloud’s extensive storage capacity, established in 2002, played a crucial role in realizing the modern version of it.

2012: The year 2012 marked a significant milestone when major internet service providers and web companies agreed to implement IPV6, expanding global internet address space exponentially. This development ensured that the IoT could accommodate the growing number of connected devices.

It evolved further with the advent of “smart cities,” employing its technologies to enhance energy efficiency, reduce waste, and optimize traffic management. Projects like “Smart City Switzerland,” initiated in 2012 by the Swiss Federal Office of Energy, exemplify the collaborative efforts of universities, businesses, and public administration to explore innovative urban solutions.

2013: By 2013, the IoT had become a multi-technology system incorporating the internet, wireless communication, micro-electromechanical systems (MEMS), and embedded systems. The scope of the IoT expanded to encompass diverse applications, from mobile phones to building maintenance to medical devices.

2015: The year 2015 witnessed the integration of smartphones into it, becoming essential communication tools monitored by marketing departments for targeted promotions. The healthcare industry embraced IoT with devices like smartwatches and smartphones tracking patients’ real-time health data.

Vehicles, including cars and trucks, became integral members, utilizing wireless networks to communicate with connected networks and extract real-time information about maintenance, driving conditions, and routes. Self-driving cars, introduced in the 1980s, joined it with cloud-based technologies enhancing their decision-making capabilities.

In summary, human neighborhoods have become interconnected as part of the Internet of Things, a dynamic and evolving ecosystem encompassing a wide array of technologies and applications. The IoT has revolutionized our daily interactions with the world, simplifying tasks, enhancing safety, and optimizing efficiency. As this technology evolves, its impact on our lives is poised to intensify. The future of it holds promise, with novel applications and use cases emerging continually.
