1. Introduction
Due to the technical development of modern micro-electromechanical systems, microelectronics, System on Chip SOC, Nano-materials, sensors, wireless communications, computer networks, distributed information processing, wireless sensor networks (Wireless Sensor Networks, WSN) and radio frequency tags (Radio Frequency Identification RFID ) In recent years, rapid development. These two technologies are independent of each other, but there are inextricably linked, they cross each other and mutual integration, with a very broad application prospects in the military and national defense, industrial and agricultural control, urban management, biomedical, environmental monitoring, emergency many areas have a major disaster relief, counter-terrorism anti-terrorism, hazardous area, remote control, logistics management, personnel identification, automotive research and practical value, has attracted the attention of domestic and international research and industry-wide. When the deepening of the development of these technologies with today's Internet technology, Internet-based expansion and extension to form a new generation of network technology, the Internet of Things was born. The Internet of Things is a development opportunity facing humanity this century, known as the first change human life. Wide range of applications of the Internet of Things will be the information revolution, computers, the Internet and mobile communication network after another.
Technology of Internet of Things has been a widespread concern in recent years. The concept of the "Internet of Things" is on the basis of the "Internet Concepts", which refers to the types of sensors and the Internet interface between new technologies. Its purpose is to make all of the items are connected to the network to facilitate the identification and management involves identifying, sensing, information transfer and processing and other key technologies. There is no doubt that if the "Internet of Things" era, people's daily lives will have seen dramatic changes.
 
2. Theory of Internet of Things
 2.1 Definition of Internet of Things
The Internet of Things is various sensing devices such as radio frequency identification (RFID) device, infrared sensors, global positioning systems, laser scanners and other devices and the Internet combine to form the a huge network. It refers to the types of sensors and the Internet interface in a new technology. Its purpose is to make all of the items are connected to the network to facilitate the identification and management involves identifying, sensing, information transfer and processing and other key technologies.
2.2 The key technologies of Internet of Things
In 2005, the ITU published a report entitled "Internet of Things", its first author, Laura, Srivastava said本论文由英语论文网提供整理，提供论文代写，英语论文代写，代写论文，代写英语论文，代写留学生论文，代写英文论文，留学生论文代写相关核心关键词搜索。
