【摘要】 无线传感器网络(WSN)是以数据为中心的网络,如何对传感器节点采集的感知数据进行有效的存储和查询访问已经成为WSN研究的重点。提出一种基于层次路由的分布式数据存储方法,降低了WSN网络的通信负载且使得网络内各节点能耗更加均衡,从而有效地延长了无线传感器网络的生存时间.更多还原

【Abstract】 Data is the center of wireless sensor network(WSN).A large amount of sensing data is generated by sensor nodes.How to store and inquire the data efficiently has become one of the research focuses of wireless sensor network.In this paper a distributed data storage method is proposed,which has organized in a gradation routes.The communications load of WSN has been efficiently reduced and at the same time it achieved a better energy balance.Therefore,this data storage method tends to prolong the lifetime of the whole wireless sensor network.更多还原
