中国科技论文在线 基于备用簇首的线性带状无线传感器网络 王伟,张申,阳媛 （中国矿业大学信电学院，徐州，221008） 摘 要：煤矿巷道具有带状的地形特点，因此本文提出了将一种带备用簇首的线性带状无线传感器网络。 这种网络区别于传统的无线传感器网络，网络的传感器节点部署在狭长的地理区域，形成一个链型拓扑结 构。同时设计带有备用簇首的层次型网络体系结构来降低网络的能耗，并通过数学公式分析了网络的能量 消耗和生命周期，最后由仿真验证了层次性结构网络的性能，大大的延长了网络的周期。 关键词：无线传感器网络；线性带状拓扑；备用簇首 A linear band-type Wireless sensor networks base redundant cluster heads Wang Wei,Zhang Shen,Yang Yuan (China University of Mining and Technology,Xu Zhou,221008) Abstract Abstract AAbbssttrraacctt: According to band-type characteristics of the environment in the coal mine tunnel, this paper presents a kind of linear band-type wireless sensor network with redundant cluster heads. Such networks are fundamentally different from traditional sensor networks in that the sensor nodes in this class of networks are deployed along narrowly elongated geographical areas and form a chain-type topology. We then propose hierarchical network architecture include redundant cluster headset which can Reduce network energy consumption，and analys e power consumption and network lifetime through mathematical formula,Simulations have been carried out to verify the performance of this hierarchical architecture network, The network lifetime is prolonged greatly.
