摘要 基于传感器网络的特性,根据查询与簇头节点的数据关联关系,对簇头节点的通信能量消耗和查询响应时间进行了分析,提出了一个估算模型,给出了节省能量优先和查询响应时间优先的算法.性能分析表明,该方法提高了查询效率,降低了传感器网络的能量消耗. Based on the characteristics of sensor network and the data correlation between query and cluster head node, the communication energy consumption and the query response time were analyzed, a model for estimation was proposed, the algorithms of energy-saving and query response time priorities were given. By analyzing the performance it shows that the method greatly enhances the efficiency of query processing and reduces the energy consumption of sensor network.
