基于DFD算法的无线传感器网络故障诊断系统的设计

Design of a Wireless Sensor Network Fault Diagnosis System Based on DFD Algorithm

为了更好地了解无线传感器网络节点的分布位置及故障情况,提出了一种无线传感器故障诊断系统的设计方案.该系统采用三边测量法实现了节点的定位,使用DFD故障诊断方法实现了节点的故障诊断,并在.NET框架的智能客户端技术基础上实现了定位信息及故障信息的处理和显示.

In order to know the distribution and the fault condition of the nodes in the wireless sensor network better, a design scheme is proposed which uses the trilateral measurement method and the DFD fault diagnosis method to achieve the node localization and node fault diagnosis. It also achieves the processing and display of the positioning information and fault information based on the smart client technology of the . NET Framework.
