摘要
无线传感器网络系统故障诊断技术的研究对提高系统可靠性具有重要意义。本文综述了近年来国内外对无线传感器网络系统故障进行诊断的技术研究,主要包括节点级硬故障、节点级软故障和网络级故障的诊断技术,并对4种主流诊断技术在诊断速度上作出比较。最后对传感器故障诊断技术的发展趋势和有待解决的问题作了一定的分析和探讨。
The research on fault diagnosis technology is important to improve the reliability of wireless sensor network system. This paper reviews recent domestic and international fault diagnosis technology research on wireless sensor network system, including node-level hardware failure, software failure and network-level fault diagnosis techniques, And four major diagnostic techniques are made a comparison over the diagnostic speed. Finally, the sensor fault diagnosis technology trends and issues are to be made a certain analysis and discussion.
