摘要
无线传感器网络(WSNs)作为传感器、微机电系统和无线网络三项技术相结合的产物,是一种全新的信息获取和处理技术,已经引起了学术界和工业界的高度重视。介绍了WSNs的体系结构、特点和应用领域,阐述了协议栈中各层的协议和WSNs的热点共性技术,并探讨了目前存在的问题和下一步的研究方向。
As a result of combination of sensor, micro-electro-mechanism system and wireless networking, wireless sensor networks(WSNs) is a novel technology about acquiring and processing information. Both academia and industries are very interested in it. The architecture, characteristics and application of WSNs are introduced. Protocols of every layer in protocol stack and hotspot common technology of WSNs are summarized and expatiated. Finally,current issues are also discussed,and the coming work is proposed.
