摘要: 文中提出一种基于超节点和能量优先的无线传感器网络的高效查询算法.该算法包括传感器节点的层次聚类算法及基于能量代价模型等支撑技术,主要解决了以下两个问题:(1)数据如何从传感器节点传送到汇聚节点;(2)通过对传感器节点进行聚类,形成超节点,使得在查询过程中减少对无关节点的访问.实验表明该算法在提高无线传感器网络查询效率的情况下,延长网络的使用寿命.Abstract: In this paper we proposed a efficient algorithm based on hierarchical clustering, this algorithm include hierarchical clustering algorithm, energy-distance algorithm. We propose to solve two problems: (1) how to send data from sensor node to sink node; (2) how to implement hierarchical clustering algorithm to produce super sensor nodes. Visit frequency to unrelated nodes is decreased. Both improve query efficiency and the network lifetime.
