Jihong Guan · Dianzi xuebao · 2008
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 storage and information brokerage techniques are discussed in detail.Following that,query processing methods are presented,including query categorization,query processing models and optimization techniques.Finally,we conclude the paper and highlight the future development of storage and access techniques of WSNs.
