中文摘要：
针对无线传感器网络中传感器节点能量有限的特点，提出了一种分层树结构的无线传感器网络分簇组网算法．算法中，将整个网络分簇架构模型分为上层和下层，上层为簇间层，下层为簇内层．网络设计开始于指派设备DD，组网过程中优先选取剩余能量高的节点作为簇头，且在簇间层启用中继节点这种新型节点将簇头连接起来，最终形成以DD为树根的多跳分层树网络．仿真结果表明了这种分层树结构的分簇算法比传统的LEACH更有效．
英文摘要：
Because of the energy limit of wireless senor networks, in this paper, we describe a cluster algorithm based on layered tree structure for WSNs. In this algorithm, the entire network structure model is divided into two layers, the upper layer and the lower layer. The upper layer is inter-cluster layer and the lower layer is intra-cluster layer. Network design begins with Designated Device（DD）, during the process of constructing network, the node with more remnant energy will be selected as cluster head preferentially and the gateway node, one new kind of node, is used to connect with cluster heads in inter cluster layer. Finally, we can get a multiple-hop layer tree network and DD is the boot. The simulation result proves that this clustering algorithm based on layered tree structure has more effectivity than LEACH.
