基于神经网络的无线网络故障节点定位技术
Wireless network fault node location technology based on neural network
摘要
Abstract
Since the traditional wireless network fault node positioning method is unable to effectively handle node power fluctuation and the fuzzy environment disturbance to the fault node location accuracy,a wireless network fault node localization method based on wavelet neural network is proposed.Three kinds of effect forms of wavelet neural network in the node fault location is analyzed.The fusion forms 1 and 3 are used to locate the redundant node failure.The wavelet neural network is taken as a predictor.The normal output of the previous sampling time is input into n wavelet neural networks in cross form to get node prediction output value of the current time.The residual error between the node prediction output value and actual output value is deduced.If the residual error value is higher than the threshold,it means that the node is fault node.The experimental results indicate that the proposed fault node positioning method can accurately position the node with additional,multiple and short trouble faults.关键词
