As an important part of the new generation of information technology, the Internet of Things has a very broad prospect. It involves a lot of electronic technology, intelligent perception, recognition technology and pervasive computing and other communication perception technology, the Internet of Things is the upgrade of the Internet era.

Through a variety of information sensing devices, the Internet of Things collects any information that needs to be monitored, connected, interactive objects or processes in real time, and combines with the Internet to form a huge network. Its purpose is to realize the connection between things and things, things and people, all items and the network, convenient identification, management and control. The perception layer and transport layer of the Internet of Things participate in many manufacturers, and become the most competitive field in the industry.

1、Wireless Sensor (UGS)

Whether it is in intelligent transportation, smart city, intelligent agriculture, industrial Internet of Things, or field disaster prevention and other fields, if humans want to achieve a comprehensive perception of the physical world, they must first ensure that the data obtained by the perception layer is comprehensive and accurate, which means that the Internet of Things system needs to arrange a large number of sensors according to the application field and specific needs. Even if necessary, it will take the way of aircraft broadcasting to carry out a large range of arrangements, so that the sensor and the Internet of things system can not be physically connected, but must use wireless channels to transmit data and communication.

2、Intelligent sensor

Intelligent sensor is a kind of intelligent data terminal equipment with environment sensing, data processing, intelligent control and data communication, which integrates sensor and microprocessor with embedded technology. It has self-learning, self-diagnosis and self-compensation capabilities, composite sensing capabilities and flexible communication capabilities. In this way, the data that the sensor feeds back to the Internet of Things system when perceiving the physical world will be more accurate and comprehensive to achieve the purpose of accurate perception.

In microelectronics, the smaller the feature size of the integrated circuit means that the higher the integration of the device, the faster the operation speed and the better the performance, and the smaller the size of the sensor in the Internet of Things system also means that the system is more convenient and the performance is better.

MEMS (Micro-electromechanical system), using traditional semiconductor processes and materials, integrates micro-sensors, micro-actuators, micro-mechanical mechanisms, and signal processing and control circuits, until the interface, communication and power supply equal to a miniature device or system. This small size, low cost, integrated, intelligent sensor system is an important development direction of future sensors, but also the core of the Internet of Things. Therefore, the field of MEMS sensors has become the top priority of relevant enterprises.

3、Wireless Ad hoc Networking

When it comes to this wireless AD hoc network, many readers may be relatively unfamiliar, but its importance cannot be ignored. Compared with traditional networks, wireless AD hoc network adopts a "peer structure" mobile communication mode that does not require base stations, and all networked devices in the network can be dynamically networked during the mobile process.
