无线传感器网络中数据存储与访问研究进展

 无线传感器网络集感知、计算和无线通信为一体,是以数据为中心的网络,因此数据存储与访问是无线传感器网络研究中的重要问题.本文围绕无线传感器网络以数据为中心这一条主线,对其中数据存储与访问的国内外研究进展进行了综述.首先概述了无线传感器网络中的数据存储与访问的概念与技术;然后详细探讨了各种数据存储策略,重点分析了分布式数据存储和信息中介;其次详细介绍了查询的分类、查询处理模型以及优化策略;最后对无线传感器网络中数据存储与访问技术进行了展望.

Data Storage and Access in Wireless Sensor Networks:A Survey

Data storage and access in wireless sensor networks(WSNs),broadly referred as to data management,specifies how data is stored and how queries are disseminated to acquire the relevant data,which has become an import research issue of WSNs.From the perspective of data-centric network,this paper surveys the state of the art techniques of data storage and access in WSNs.First,the basic concepts of data storage and access in WSNs are introduced,then data storage strategies are summarized,and distributed data sto...
