摘　　要：提出了一个无线传感器网络多查询的节能优化方案。该方案通过建立相似查询判断算法把多查询中的相似查询分为一组,并在每一组找一个能使传输能耗达到最小的中继节点作为处理节点。组内节点的数据都传送到该处理节点,并由该节点利用数据处理函数处理数据,然后再传到基站。这样就减少了网络中数据的传输量,从而有效地节省了网络的能量,达到能量的最大化利用。This paper judges the similar query in multi-queries by establishing the similar query algorithm, and divides the similar query into a group. In each group, a node that can make the minimum transmission consumption is selected as a relay node. The source data of all nodes within a group are translated to the relay node, and the relax node processes data using the data processing function and forward the result to the sink. As a result, the scheme can greatly reduce transmission energy consumption of multi-queries, effectively save energy, maximally use the energy of network.
