英文摘要： The proposal is trying to design and construct a kind of wireless sensor network for spectrum monitoring over border area of Yunnan province. Our purpose is to solve the problems of the limited monitoring coverage and the lack of monitoring in some special areas due to diversity of radio environment and few expensive radio monitoring stations over the area. The WSN for spectrum monitoring designed by us will be based on the existing research foundations of our lab and the WSN features, such as easy to deploy, self-organization, low-cost and real-time. By using the typical study methods, including of system modeling, mathematical analysis, simulation, embedded node and experimental platform development, we will adopt the relevant principles of sensor actuator networks, cognitive radio network and cooperative communication to build a spectrum monitoring WSN with the characteristics of layered architecture, distributed detection and interconnection of heterogeneous network. The proposal will focus on the modeling of hierarchical network system, distributed data fusion, topology control and routing algorithm, DHCP-based addressing and access mechanism, ARM-based node and experimental platform design, performance testing and analysis. Meanwhile, our work will achieve the required performances of the network that are reliable connectivity, fast topology reconstruction, effective locating and routing mechanism, real-time information transmission and economical energy consumption.
