Considering the facts that the nodes energy of wireless sensor network is limited and the node lifetime is easily affected by the whole network node energy, in order to reduce the influence of the ordinary life of the nodes, this paper proposes a heterogeneous network model to achieve the election of the different regions within ordinary nodes.Based on the common residual energy of the nodes and ordinary nodes, the node probability to be the cluster head node to node distance weight coefficient Sink is determined, and the cluster head region ordinary nodes and the cluster head node are established. By choosing the cluster head node threshold value, the cluster head node is determined to realize the data transformation from the common node of the cluster region to the cluster head. What's more, the entire network life is prolonged by reducing the energy consumption of the network.%针对无线传感器网络中节点能量有限,节点寿命易受整个网络节点能量的影响,为了减少普通节点对整个网络寿命的影响,文中提出了一种基于异构网络模型实现对不同区域内普通节点进行选举,并引入普通节点剩余能量和普通节点到Sink节点的距离的权重系数来确定节点成为簇头节点的概率,并将簇头区域内普通节点和簇头节点建立簇区,通过选取簇头节点的阈值来确定簇头节点,从而实现本簇区域下普通节点向簇头传递数据信息,减小能耗对整个网络寿命的影响来延长整个网络的寿命.
