摘　　要：提出一种能量高效的传感器网络数据查询路由EEDQ(energy-efficientdata query),EEDQ以sink节点为根节点,构造最小路由生成树,由sink节点发出查询任务,查询结果由叶子节点向sink节点传输,传输过程中进行数据汇聚。实验表明,EEDQ相比direct transmission,大大提高了传感器网络的生命周期。This paper proposed an energy-efficient data query （EEDQ） protocol for wireless sensor network, in which designed a minimum spanning tree with the sink node as root, query task was flooding from the sink along the tree, and transmitted query results from the leaves nodes toward the sink node, in the same time, aggregated data in the parents nodes. Experimental results show that the EEDQ protocol algorithm can lead to the increase of sensor network lifetime compared with direct transmission.
