For the limited energy problem in the monitoring environment of wireless sensor networks(WSN),an intellective distributed intelligent energy-saving method for the WSN is presented based on the insects-collaboration mechanism.An analogy between the WSN energy-saving and the insects-collaboration is made.A source node selection algorithm using the insects-collaboration mechanism is proposed to choose the most suitable node for data sampling and transmission.As well as satisfying the accuracy of monitoring,the threshold of the source node selection probability is modified in real-time according to the information distortion,so that the amount of the interaction of network information and the network energy consumption are reduced.The simulation results show that,compared with the existing energy-saving methods,the proposed method has higher reliability and smaller energy consumption.It can optimize the number of nodes according to the requirements for the accuracy of monitoring and the source node selection algorithm,reduce energy consumption reasonably and dynamically,and prolong the lifetime of WSN.
