摘要
集传感器技术、无线传输技术、网络通信技术、分布式信息处理技术与编程技术于一体而形成的无线传感器网络(WSN),是一种全新的信息获取和处理系统,具有十分广阔的应用前景。介绍了无线传感器网络WSN的发展历程和现状,论述了无线传感器网络WSN系统的构成,阐述了WSN系统的主要技术指标和设计特点。同时,结合实际应用,对无线传感器网络系统的架构、网络通信模型结构以及当前的主要应用领域作了深入地探讨和研究,最后指出了当前WSN关键技术亟需解决的问题。
WSN（wireless sensor network）, in integration of sensor technology, wireless transmission technology, network communication technology, distributed information processing technology and programming technology, is a completely new system for information acquisition and processing, and thus of a broad application prospect. This article gives the development process and present situation of the wireless sensor network, discusses its constitution, tells of its principal technical indexes and design feature. Meanwhile, in combination of the practical application, this paper explores in depth the framework, network communication model structure and main application domain of the wireless sensor network. Finally it points out the critical problems for prompt solution in WSN technology.
