摘要:针对无线传感器网在数据查询过程中存在的问题,提出一种基于时间/能量模型的无线传感器网查询优化算法,每个传感器站点通过评估数据/事务的时限要求和时间/能量消耗,将查询数据直接上传到服务器,并执行压缩、合并、聚集/融合等优化处理。仿真实验结果表明,该算法是有效的,且能够获得较好的性能。
Aiming at the problems existed in process of data query in Wireless Sensor Network(WSN), a novel query optimization algorithm based on time/energy model is proposed. Each sensor site transmits the query data to server according to the evaluation of the time constraints and the time/energy consumption. Some optimization operations such as compression, merging, and aggregation/fusion are made. Simulation experimental results show this algorithm is effective and can gain better performance.
