IoT Introduction

1. Internet of Things ( IoT ) By Prof. Pratik De Sarkar Department of EEE, IEM, Kolkata Lecture-1: Introduction

2. IoT Protocols The Internet of Things ( IoT ) is about the network of sensor devices to the web in real-time. IoT devices communicate with each other over the network, so certain standards and rules need to be set to determine how data is exchanged. These rules are called IoT Network Protocols. Today, a wide variety of IoT devices are available, and therefore different protocols have been designed.

3. IoT Architecture IoT technology has a wide variety of applications. Depending upon different application, it works accordingly as per it has been designed/developed. So we need a standard defined architecture of working which is strictly followed universally. Basic fundamental architecture of IoT has 4 Stages Sensing Layer Network Layer Data processing Layer Application Layer

4. Web of Things Undoubtedly, the internet of things, or IoT , has made our lives simpler, but as the quantity of gadgets in our environment grows, so do the complications that come with it. A major obstacle to the IoT's mainstream acceptance has been the complexity of controlling and connecting with so many devices. Ten smartphone apps are required in order to interact with your ten IoT devices. As you would have to move between apps, this won't be very handy. Unfortunately, this is the scenario with most IoT devices. The worst thing is that the IoT hasn't been able to reach its full potential since the majority of these protocols and standards are incompatible with one another.

5. Web of Things The internet of things, which enables data interchange, is not complete until devices are connected to the internet and assigned IP addresses. But that doesn't mean that gadgets will interpret it correctly. In order to enable device communication, we require a system similar to HTTP, which is a universal means of transferring data in the form of text, pictures, sound, and other media components. In order to link everything in the real world and give it a presence on the World Wide Web, the Web of Things, or  WoT , uses and adapts Web protocols to fill this gap.

6. Web of Things Web of Things ( WoT ) refers to a set of standards formed by the world wide web consortium (W3C) to facilitate the interoperability, fragmentation, and usability of the Internet of Things ( IoT ). In other words, it is a subset of the internet of things ( IoT ) and is built around software standards such as REST ( REpresentational State Transfer), HTTP, and URI (Uniform Resource Identifier) to allow devices to interact with one another.

8. Android things Along with Google-certified hardware, a method to provide regular software and security upgrades for the connected devices, and a highly optimized operating system that can operate on low-powered devices and interact with any hardware platform, are all included in the Android Things package. Android Things is an obsolete embedded operating system platform from Google, released in 2018 On January 5, 2021, the Android Things Dashboard went down. The Android Things Dashboard was fully shut down and all of its remaining data was erased on January 5, 2022.
