摘要
无线传感器网络(Wireless works,WSN)是当前在国际上备受关注的、涉及多学科高度交叉、知识高度集成的前沿热点研究领域。传感器技术、微机电系统、现代网络和无线通信等技术的进步,推动了现代无线传感器网络的产生和发展。无线传感器网络扩展了人们信息获取能力,将客观世界的物理信息同传输网络连接在一起,在下一代网络中将为人们提供最直接、最有效、最真实的信息。无线传感器网络能够获取客观物理信息,具有十分广阔的应用前景,能应用于军事国防、工农业控制、城市管理、生物医疗、环境检测、抢险救灾、危险区域远程控制等领域。已经引起了许多国家学术界和工业界的高度重视,被认为是对21世纪产生巨大影响力的技术之一。
数据融合技术是无线传感器网络的一个关键技术, 能减少传感器节点间的传输量,从而明显提高网络感知效能,延长网络生命周期, 减小时间延迟。无线传感网数据融合,是对源数据或信息的获取、表示及其内在联系进行综合处理和优化的技术。传感器只能获得环境或被测对象的部分信息段,而传感网信息经过融合后能够完善地、准确地反映环境的特征。传感网目标的融合识别是试图将各传感器关于目标的不精确,不完全的数据进行融合,产生较单一传感器更精确,更完全的属性估计和判决。数据融合技术已经广泛应用于信息电子学、计算机科学、自动化等领域。

Abstract
Wireless work (Wireless works, WSN) is the current focus on international knowledge, involving multidisciplinary highly cross, highly integrated the leading edge of the hot research field. Sensor technology, mems, the progress of work and munication technology, to promote the emergence and development of modern wireless work. Wireless work (WSN) expanded the people access to information, with the objective world of physical information work connection together, in the heart of the next work for people to provide the most direct, the most effective and most real information. Wireless 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 work (WSN) can reduce the magnitude of the transmission between the sensor nodes, thus significantly increase the efficiency of work awareness and prolong work life cycle, reducing
