The Internet of Things (IoT) is an ever-growing network of interconnected devices, ranging from sensors and appliances to vehicles and industrial equipment. These devices communicate with each other and with the cloud to collect and exchange data, enabling automation and smart decision-making. IoT network protocols play a crucial role in enabling these devices to communicate effectively and securely.
Choosing the right IoT network protocol depends on various factors, such as the type of device, the network topology, the data requirements, and the security needs.
