摘　　要：传统无线传感网部署过程中仅采取单簇头机制,因而稳定性不足,对此提出了一种基于双簇头优化机制的WSN稳定传输算法。文章采用非均衡划分机制,将网络区域按照种子聚类予以初始化划分,设计了一种新的网络初始化方法,降低因簇头节点过载而出现的“热点”,以规避节点抖动而出现网络传输波动的问题,从而起到稳定簇内传输质量的作用。结合簇头能量变化情况,构建了能量—周期更新阈值,利用该阈值将能量较差的被选节点予以剔除,从而提高了网络链路抗抖性能,避免所选簇头因能量受限而导致出现难以控制簇成员节点的现象,以增强簇头节点对网络区域的控制能力并稳定网络传输流量,提升节点在高强度数据传输环境下的生存能力。仿真实验表明,与当前较为流行的WSN传输技术相比,所提算法具有更高的网络稳定传输时长和更低的链路周期抖动概率。The deployment of traditional wireless sensor networks only uses single cluster head mechanism,it may lead to insuf-ficient stability.Hence,a WSN stable transmission algorithm based on double cluster head optimization mechanism is pro-posed.Using the unbalanced partition mechanism,the network area is initialized and divided according to the seed cluster,and a new network initialization method is designed to reduce the"hot spots"caused by the overload of cluster head nodes,so as to avoid the problem of network transmission fluctuation caused by node jitter,and to stabilize the transmission quality in the clus-ter.The energy cycle update threshold is constructed in combination with the energy change of the cluster head,and the select-ed nodes with poor energy are eliminated by using the threshold.It improves anti chattering performance of the network link,and avoids the phenomenon.It is difficult to control the cluster member nodes due to the energy limitation of the selected clus-ter head,hence,the method enhances the control ability of the cluster head nodes to the network area and stabilizes the net-work transmission traffic,improves the survivability of nodes in high-intensity data transmission environment.Simulation re-sults show that the proposed algorithm has higher network stable transmission time,lower link cycle jitter probability and ex-cellent transmission performance.
