无线传感器网络路由协议的设计将如何有效的利用能量,延长网络的生命周期作为首要研究的问题。分簇协议LEACH将无线传感器网络节点组织成簇,通过数据融合,可以有效降低数据传输量,减少节点通信开销,延长网络生存时间。为了使簇头节点不会因负载过重而能量过早耗尽,很多文献给出了不同簇头选择策略的分簇算法。 The design of wireless sensor network routing protocol will be how to effectively use the energy to extend the life cycle of the network as the primary research issue. Clustering Protocol LEACH organizes nodes of wireless sensor networks into clusters. Through data fusion, LEACH effectively reduces data transmission, reduces node communication overhead and prolongs network lifetime. In order to prevent the cluster head node from being depleted prematurely due to the heavy load, many literatures give the clustering algorithm of different cluster head selection strategies.
