无线传感器网络主要任务是数据采集,在许多的应用场合对传感器网络数据可靠传输有较高的要求,但由于传感器节点容易失效,导致数据无法正确传输,因此故障检测是确保数据信息正确收集的重要保障.本文中提出了一种基于分簇网络拓扑的实时故障检测算法（CRFD）,能够在网络划分的不同簇中自发地完成故障检测,正确诊断出节点的状态.分析了算法的性能,并通过仿真实验,表明与＂基于比较的故障检测算法（CBFD）＂相比,CRFD算法具有更小的系统开销,从而有效节省节点能耗.

Collecting data is the main task of Wireless Sensor Network(WSN).In many applications,WSN must be able to guarantee highly reliable data transmission.Since sensor nodes appear failure frequently,the node failure detection is very import to accurately data collection.In this paper,in order to detect the right node state,we proposed a Cluster-based Real-time node Failure Detection(CRFD) scheme.In this scheme,failure detection can be performed by every cluster spontaneously.The method,through the analyzing and simulation,reveals that there is fewer system costing and node energy-consumption than the Comparison-Based Failure Detection(CBFD) scheme.
