摘　　要：针对工业环境大型设备的状态监测,对无线传感器网络节点及网络结构进行优化.将网络节点分为3个级别,并分别进行能耗及功能设计,综合提高网络生命周期.分析了大型设备周边无线信道特征,针对小尺度衰落及设备运转时对信号的随机遮挡,提出一种多簇头协作式超簇结构的无线传感器网络.仿真结果表明,超簇结构无线传感器网络的网络连通度及网络生存期明显优于传统无线传感器网络.Aiming at the monitoring status of large-scale equipment in industrial environment,the architecture and node configuration of wireless sensor networks are optimized.The nodes are classified into three types with different power dissipation and functionality in order to prolong the survival time of the whole network.A new type of wireless sensor network with super-cluster head cooperative architecture is proposed based on analyzing the characteristics of wireless channel around the large-scale equipment.Simulation results show that the connectivity and survival time of the new network are superior to the traditional wireless sensor networks.
