Abstract: Regarding to the situation that the wireless sensor networks have limited energy and require energy -saving,an optimally scaled clustering algorithm for network have been proposed in this paper.Moreover taking the heavier burden of cluster heads into account,the node that has higher residual energy is chosen as the cluster head, which can effectively extend the lifecycle and improve the efficiency of the use of WSN.Finally,with the way of coordinating the adaptive weighing -estimation data aggregation algorithm measurement variance of to integrate the collected data,reduce the data transmission,further to achieve the effect of energy saving.
