Sensor technology, mems, the progress of modern work and wireless munication technology, to promote the emergence and development of modern wireless sensor work. Wireless sensor work (WSN) expanded the people access to information, with the objective world of physical information transmission work connection together, in the heart of the next generation work for people to provide the most direct, the most effective and most real information. Wireless sensor work (WSN) can obtain the objective physical information, has the very broad application prospects, and can be applied to military defense, industrial and agricultural control, urban management, biological, medical, environmental detection, remote control in areas such as disaster relief, the dangerous area. Has attracted the attention of the academia and industry in many countries, is considered to be one of produce great influence to the 21st century technology. Data fusion technology is a key technology of wireless sensor work (WSN) can reduce the magnitude of the transmission between the sensor nodes, thus significantly increase the efficiency of the work awareness and prolong the work life cycle, reducing the time delay. Wireless sensor work data fusion, is the source of data or information access, said and inner link of integrated processing and optimization technology. Sensors can only obtain the environment or the part of the object information, and sensing work information after fusion can perfectly and accurately reflects the characteristics of the environment. Sensing of mesh mark about target fusion recognition is trying to each sensor imprecise, inplete data fusion, produces more accurate than the single sensor, more plete property estimation and decision. Data information fusion technology has been widely used in electronics, puter science, automation, etc. Keywords: Sensor Networks Sensor applications Wireless sensor classification sens Sensor works, Inter of things 目 錄 III 目 錄 摘 要 .............................................................................................................................
