摘　　要：近年来,无线传感器网络基于事件查询的算法引起很多国内外学者的关注,也因而产生了不少的相关算法,它们大多主要体现在节点移动上。本文主要分析了现有的窗口查询算法的优缺点,针对当窗口中某个查询节点没有被收集而造成的空洞现象进行处理,以及在选择下一查询节点时考虑能量与距离的因素,提出新算法EQA(effective area query algorithm)。通过对算法进行仿真与分析,并与IWQE和ESA算法进行对比,结果显示新算法在网络耗能、查询质量、网络生命周期等方面都得到提高。In recent years, algorithms based on event queries in wireless sensor networks cause the attention of many scholars at home and abroad. It produces a number of related algorithms based on the mobile nodes mostly. This paper analyzes the advantages and disadvantages of the existing window query algorithm. Aiming at the hole phenomenon by the case of a query node not collecting, and taking energy and distance into consideration when choosing the next query node, a new algorithm EQA （effective area query algorithm） is put forword. Finally, this paper simulates and analyzes the algorithm and compares it with IWQE algorithm and ESA algorithm. The result shows that the new algorithm is superior to IWQE and ESA algorithm in energy consumption, query quality, network lifetime and so on.
