摘　　要：在无线传感器网络中,为了监测多个事件,监测区域可能需要布置多种不同类别的传感器节点以监测不同的事件属性,通过对每个传感器节点感知属性信息的融合处理,来判别事件是否发生。如何快速地查询到相应事件的当前状态是个重要的研究课题。本文将分布式事件存储、语义路由以及查询算法相结合,提出了一种基于语义路由的事件查询算法。在该算法中,一个传感器节点只需要关心自己通信范围内的邻居节点,不需要知道整个网络的状况,算法具有冗余数据少、查询能耗小,网络生存周期比较理想、实现简单等特点。In wireless sensor network, in order to inspect many kinds of incidents, it might be necessary to dispose sensor nodes of different sorts in the inspecting area to inspect different observational attributes. Whether an incident occurs is judged through fusion and processing of the attribute information that every sensor node inspects. How to find the current state of corresponding incident is an important research problem. In this paper, an incident query algorithm based on semantic routing is proposed though combining distributed incident storage, semantic routing and query algorithm. In this algorithm, every sensor node only concerns the nodes in its own communication range instead of knowing all the nodes in WSN. This algorithm features less redundant data, lower query consumption, longer lifetime and easier implementation.
