Exploring the Distinctions: Understanding the Difference between Web of Things and Internet of Things
Introduction
With the advancement of technology, the terminology used to describe it has also evolved. One of the most commonly heard phrases nowadays is the Internet of Things (IoT). But have you heard about the Web of Things (WoT)? Although both these terms sound similar, they are quite distinct from each other. In this article, we will explore the difference between Web of Things and Internet of Things.
The Internet of Things (IoT)
The Internet of Things (IoT) refers to a network of interconnected devices equipped with sensors and software that can communicate with each other. This allows the devices to collect and exchange data, which can be used to automate and optimize various processes. For example, a smart home equipped with IoT devices can automatically adjust the temperature, lighting, and security systems based on the user’s preferences and behavior.
The scope of IoT is vast, and it includes various domains such as healthcare, transport, agriculture, and manufacturing. IoT has the potential to revolutionize the way we live and work by providing real-time insights and increased efficiency.
The Web of Things (WoT)
The Web of Things (WoT) is an extension of IoT, where the devices are connected to the World Wide Web (WWW) instead of a closed network. This means that the devices can be accessed and controlled remotely via the internet.
WoT offers various benefits such as increased accessibility, interoperability, and compatibility. For example, a user can control their smart home devices from anywhere in the world using a web browser or a mobile application.
The Differences between WoT and IoT
One of the key differences between WoT and IoT is the networking protocol used. IoT devices typically use a specialized networking protocol, such as Bluetooth or ZigBee, to communicate with each other. In contrast, WoT devices use standard web protocols, such as HTTP and WebSocket, to communicate over the internet.
Another difference is the level of interoperability and openness. WoT devices are designed to be highly interoperable, which means that they can work with other devices and platforms regardless of the manufacturer. In contrast, IoT devices may be closed systems that can only communicate with devices from the same manufacturer.
Examples of WoT and IoT Devices
To illustrate the difference between WoT and IoT devices, let’s look at a few examples.
Smart thermostats, such as Nest, are examples of IoT devices. They use proprietary protocols to communicate with other smart devices in the user’s home.
In contrast, the Philips Hue lightbulbs are examples of WoT devices. They can be accessed and controlled using a web browser or a mobile application, making them highly interoperable.
Conclusion
In conclusion, while WoT and IoT may sound similar, they are quite different from each other. IoT devices are connected through a closed network, while WoT devices are connected to the World Wide Web. WoT devices offer increased interoperability and openness, making them easier to use and integrate with other devices and platforms. Understanding these distinctions is essential in choosing the appropriate technology for your needs.
