摘　　要：针对无线传感网自组网拓扑结构中节点能量消耗大、能耗不均衡的缺点,构建了分布式的二级分簇线形拓扑结构。协议改进了随机放置节点的自组网方式。灌溉子网根据剩余能量的大小确定二级簇首,未承担二级簇首的簇内节点等概率竞争,灌溉子网中未承担二级簇首的簇内节点等概率竞争,并根据剩余能量的大小确定二级簇首;簇内采用单跳的通信方式,簇间采用单跳与多跳相结合的通信方式。仿真试验结果表明,分布式的二级分簇线形协议在节点生存时间和数据包发送成功率方面明显优于自组网方式。Aiming at the defects of the nodes in WSN ad hoc topologic structure, e. g. , high energy consumption and uneven energy consumption, the distributed two-level linear clustering topologic structure and relevant protocol are proposed. The protocol improves the ad hoc mode in which the nodes are placed in random. In irrigation sub-network, the head of two-level clustering is determined in accordance with the residual energy, the cluster nodes that not being the cluster head are competing based on equal probability. The single hop communication mode is used within cluster; the combination of both multiple hop and single hop modes is used between or among clusters. The results of simulation show that the distributed two-level linear protocol is better than ad hoc network in node survival time and successful transmit rate of data packets.
