采用分簇管理的无线传感器网络,能够显著地节省了能量.簇头在数据的汇总、融合、转发过程中起到关键作用,因此,一旦簇头被俘,存储的密钥信息泄露,将影响整个簇的安全通信.为有效延长网络寿命和可信簇头选举,本文设计了一种基于模糊决策的簇头选择算法作为密钥连通的基础,以剩余能量、信任值、向心度和共享密钥数作为安全性评估的关键指标.实验结果表明,通过模糊决策方法选取簇头能均衡能耗,提高网络生命周期并能阻止恶意节点成为簇头.

　　Clustering is a method to make the consumed energy efficient in wireless sensor networks, and the cluster head plays a key role in the process of data aggregation, fusion and forwarding.Once the cluster head is captured, it will affect the communication security of the whole cluster.In order to prolong the network lifetime efficiently and increase the possibility of trusted nodes being cluster-head in the process of election,this paper proposes a cluster head selection algorithm based on fuzzy decision, which choose the residual energy, nod...
