摘要:
针对无线传感器网络(WSN)监测环境中传感器节点的能量限制问题,借鉴昆虫群体协作机理,提出了一种智能的分布式节能优化方法。将无线传感器网络节能问题与昆虫群体协作问题进行了类比。利用昆虫协作机理,提出源节点筛选算法,选择最优源节点参与数据采集和传递。在满足监测精度的基础上,根据信息失真度实时修正源节点选择概率阈值,以减少网络信息交互量,降低网络能耗。仿真结果表明:该节能方法比现有的节能方法可靠性高,能耗更小; 可以根据环境监测精度要求及源节点筛选算法,优化节点数目,合理地动态控制网络能耗,有效延长网络寿命。
Abstract:
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.
