由于无线传感器网络节点存在能量供应受限、部署环境恶劣以及自身属性等因素，本文提出了一种无线传感器网络节点修复机制，即调用备份节点的修复方法，并且在节点某些部分出现故障的情况下，可以唤醒备份节点，通过改进的KNN算法选择的备份节点，可以独立、动态地重建无线传感器网络；最后通过omnet++仿真平台进行了实现，结果表明该方法能有效地实现节点的修复，提高了无线传感器网络的容错性和鲁棒性。
Because of the wireless sensor network nodes exist energy supply constraints, deployment environment bad and their own property factors, this paper puts forward a wireless sensor network node repair mechanisms, namely a repair method of calling backup node, and in the case of some parts of the node failure, it can awaken backup node, the backup node selected through improved KNN algorithm, it can be independent, dynamic reconstruction of wireless sensor network, finally it is implemented through OMNet++ simulation platform, the results show that this method can effectively achieve the repair of the node, it improves the wireless sensor network fault tolerance and robustness.
