IoT communication is one of the most important aspects of learning the Internet of Things, communication, in general, is probably the most important part of humans too, we can communicate effectively with each other that’s why we are the most intelligent species on earth, we communicate to exchange ideas, thoughts and to make our point, and making a machine or a device that can communicate with other devices is one of the most challenging parts, but rewarding too. Inspiration to make machines comes from our deep knowledge of nature. We try to mimic nature in our artificial work, and that’s why our work is effective too. So we can say that without proper and effective communication there’s no Internet of Things. In this section, we’ll learn about some effective communication protocols and learn them in detail and see where we can apply them.
