摘要：由于无线传感器部署环境复杂多样、网络拓扑动态变化、节点资源受限且易受攻击破坏，造成节点故障失效而导致网络性能急剧下降甚至瘫痪。鉴于及时有效地故障诊断和网络重构直接关系到无线传感网的平稳可靠运行，针对无线传感网的故障诊断和网络重构机制进行了系统研究。首先，分析了无线传感网故障的根源并归纳说明了当前常用的网络故障诊断方法；接下来，阐述了几种有效的网络拓扑重构算法，进而给出了一种可行的基于故障诊断的网络拓扑重构方案。该方案能够一定程度上增强无线传感网的整体生存性。

Abstract: Due to the complex and diverse deployment environment of wireless sensor, the dynamic change of network topology, the limited resources of nodes and the vulnerability to attack, the failure of nodes leads to the sharp decline or even paralysis of network performance. Since timely and effective fault diagnosis and network reconfiguration are directly related to the stable and reliable operation of wireless sensor networks, this paper mainly studies the fault diagnosis and network reconfiguration mechanism of wireless sensor networks. Firstly, this paper analyzes the root causes of wireless sensor network fault, and summarizes the current common network fault diagnosis methods; secondly, it describes several effective network topology reconstruction algorithms, and then gives a feasible network topology reconstruction scheme based on fault diagnosis, which can enhance the overall survivability of wireless sensor network to a certain extent.
Key words: wireless sensor network; fault diagnosis; network reconfiguration; network topology
