Abstract


The Internet of Things technology (IoT) is considered as the third wave of the World’s information industry after personal computer and the Internet. It has increasingly become the focus of global concern. The Wireless Sensor Network, as the key technology of the implementation of IoT, is highly valued by many countries. This paper’s wireless sensor network topic is major national special project. The design of the program in this paper is based on the three-tier sensor network architecture, and it aims to achieve the function of whole wireless sensor network. This paper focuses on the seconde level of three-tier sensor network architecture, the medium and high speed wireless sensor network.The medium and high speed wireless sensor network is to meet people’s multimedia information needs application. It requires system with better real-time and higher transfer rates. Currently, there are servaral important and pivotal techlonogies to be solved for it, including the architecture and standard of wireless network, the integration and procession techlonogy of information and so on. This paper makes a exporation and research toward the implementation of the medium and high speed wireless sensor network. Through the comparison of several wireless network technologies in performance and implementation difficulties, the WiMAX technology is chosen as the implementation technology of medium and high speed wireless sensor network. The main work in this paper includes:1. According to the demand for medium and high speed wireless sensor networks, the paper proposes implementation of medium and high speed wireless sensor network which is based on WiMAX technology. It describes the design and configuration of equipments.2. Based on the configuration of equipments above, the requirements analysis of WiMAX base board in the equipment is made. And then, base board’s overall framework is set up according to software radio system architecture and functional modules are partitioned.3. Detailed design every module including base processing module, clock and interface module, AD module, DA module and power module.4. Debug the system integrally and make verification of function of system.5. Help software engineer to complete communication debug of the base board.After the system testing, it prove that the software radio hardware platform designed in this paper and based on WiMAX is stable and reliable, and it can satisfy the system design requirement.
