摘要： 无线传感器网络可以看作是以节点感知、存储数据为基础的分布式数据库系统。针对多查询处理问题，提出一种以节能为目标的查询架构体系，以及多查询的分类算法和查询融合算法。通过实验验证了算法的有效性，即在同等条件下，可以有效节省传感器网络能量的消耗，进而延长网络的生命周期。

Abstract: Wireless Sensor Networks(WSNs) is regard as a distributed database system, in which the sensor nodes sense and store data. Aiming at query multi-queries processing problems, this paper presents a new Multi-Queries Framework(MQF) system with the primary purpose of energy-saving, under the framework, and discusses multi-queries classification algorithm and multi-queries aggregation algorithm. Experimental results show that the algorithms can effectively save the energy consumption and prolong the network lifetime on the same query conditions.

Key words: distributed sensor database, Multi-Queries Framework(MQF) system, multi-queries aggregation algorithm
