The Internet of Things (IoT) refers to an \"internet where everything is connected.\" It is an extension and expansion of the Internet, forming a vast network by integrating various information sensing devices with the Internet, thereby enabling interconnection among people, machines, and objects at any time and in any place. The Internet of Things is an important component of the new generation of information technologies. The IT industry also refers to it as \"ubiquitous connectivity,\" meaning that everything is connected to everything else. Thus, “the Internet of Things is an internet where things are connected to each other.” This has two meanings: First, the core and foundation of the Internet of Things remains the Internet itself; it is a network that extends and builds upon the Internet ； Second, its client side has been extended to any item pair to enable information exchange and communication. Therefore, the Internet of Things is defined as a network that uses information sensing devices such as radio frequency identification, infrared sensors, global positioning systems, and laser scanners, in accordance with established protocols, to connect any object to the Internet for information exchange and communication, thereby enabling intelligent identification, positioning, tracking, monitoring, and management of those objects.
