中文摘要：

在传感器网络中,分簇是其他应用的基础,本文结合传感器网络的节点特性和位置信息,提出一种基于域的分布式自动成簇算法DCAM（Distributed Clustering Auto Model）,DCAM把传感器网络按域划分来构建簇,簇之间是相互连通并且可以覆盖网络中所有的传感节点,簇头节点与簇中的网关节点就构建成网络的连通核,当传送数据时,传感节点只需在连通核中寻径,因而能明显减少寻径时间复杂度并且具有更好的分布性 然后在DCAM的基础上提出了簇的自愈和更新算法,更新和自愈算法可更大程度地延长整个网络的生命周期.

英文摘要：

Clustering is the basic of other applications such as routing,query processing etc.Considering the characteristics and location information of nodes in sensor networks,a modified directed transfer model of sensor networks,and a novel clustering algorithm based on area DCAM（Distributed Clustering Auto Model） are proposed.Theoretical analysis and simulation show that the above new methods can reduce the energy costs of nodes in data transferring efficiently for sensor networks.So,it can prolong the lifetime of the whole networks to a greater degree.
