The development and application of the Internet of things Major:Transportation engineering Reporter: Deng Yanling Liu Pihui Abstract: In this paper, the concept and definition of Internet of things are introduced firstly, expounding the architecture and the core technology of it，and then，the author introduces several applications of the Internet of things in all kinds of aspects. Finally, it make a summary of opportunities and challenges of the Internet of things encountered now. Key words： the Internet of things；RFID; GPS 1. Introduction The Internet of things is an important part of a new generation of information technology. As the name suggests, the Internet of things is something connected to the Internet, which has two meanings as follows: on the one hand, the core and foundation of the Internet of things is still the Internet, a extended and expanded Internet based on the network; on the other hand, the client of it extended between any goods and goods, for information exchange and communication.In fact, the Internet of things is the network connecting objects and objects. Considering the intelligent recognition and pervasive computing technology widely used in network,the Internet of things is called the third wave of world information industry development, after the computer and the Internet. Definition The definition of the Internet of things is putting all items, in accordance with the contract agreement, connected to the Internet by the information sensing devices, such as laser scanner, radio frequency identification (RFID), infrared sensors, global positioning system (GPS) and so on, doing some information exchange and communications, to realize intelligent identification, location, tracking and monitoring and management. Architecture and core technology 3.1 The architecture of the Internet of things The Internet of things can be divided into three layers: perception layer, network layer and application layer. Fi
