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.
