摘　　要：为了更准确地捕获网络空间中的攻击节点,提出一种光纤传感网络空间中攻击节点捕获方法。首先利用传感电路以及信号采集模块实时采集扰动信号,采用级联离散小波变换方法对信号实施去噪处理。然后通过基站向网内节点发送测试数据包,要求将数据包转发至邻居节点,并监视处理转发过程。节点对比基站和邻居节点发送的数据包,对邻居节点的可疑性进行投票。基站根据节点投票结果判断攻击节点,完成对空间中攻击节点的捕获。测试结果表明:该方法能够更准确地捕获光纤传感网络空间中的攻击节点,且能量消耗较低。In order to capture attack nodes in network space more accurately,a novel attack node capture method in optical fiber sensor network space is proposed.Firstly,the sensor circuit and signal acquisition module are used to collect the disturbance signal in real time,and the cascade discrete wavelet transform method is used to de-noise the signal.Then,test packets are sent to the nodes in the network through the base station,and the packets are required to be forwarded to the neighbor nodes,and the forwarding process is monitored and processed.The node compares the data packets sent by the base station and the neighbor node to vote the suspicious of the neighbor node.Base station judges attack nodes according to the voting results of nodes to complete the capture of attack nodes in space.The test results show that this method can capture attack nodes in the space of fiber optic sensor network more accurately and has lower energy consumption.
