摘　　要：无线传感器网络集成了传感、无线通信、嵌入式计算、微机电系统(Micro-Electro-Mechanism System,简称MEMS)以及微电子(如SOC)等各项技术,能够协同地实时监测、感知和采集各种环境或对象的信息,并对其进行处理,通过特定的网络技术将需求的信息传送给用户;该项技术的研究为解决未来10年中一个最具有挑战性的问题———“最后一米”的数据采集与通信问题,提供了一条有效途径,可以应用在国防军事、环境科学以及智能家居等等各个领域;文中首先介绍了无线传感器网络的概念、特点与应用背景,接着简述了该项技术的研究内容、设计目标以及国内外研究状况,最后,剖析了无线传感器网络的节点以及网络体系结构、算法和协议等研究热点并提出了需要进一步研究的问题。Wireless Sensor Networks is an convergence of sensor technology, wireless communication technology, embedded computing technology, MEMS technology and System On Chip technology. It can not only monitor and acquire data from environment and observe object cooperatively and real timely, but also transmit the processed information to users with a special network technology. This advanced technology gives a way to resolve the “ last meter” data sensing and communicating problems in next decade, and it can be used in varies application areas, such as military, environmental science and smart home environment. The concept, characters and application background are introduced firstly. Then the research issues, design targets and research status are depicted. Finally, open research issues for the realization of sensor networks are discussed based on the outline of the node＇ s structure and communication architecture for sensor network and exploration of algorithms and protocols in the literature.
