基于网格结构无线传感网络故障诊断算法

无线传感网中节点的数据信息具有空间相关性,可以通过邻居节点数据的比较来完成网络的故障诊断。网络中有时会出现瞬时故障,影响网络的诊断精确度。文中提出了一种基于网格结构的无线传感网络故障诊断算法,算法通过相邻节点历史数据信息之间的比较来确定节点最终状态,有效地避免了瞬时故障对节点诊断的影响。仿真结果表明,文中算法可保证较高地诊断精确度并能节省一定的能量。

A Fault Diagnosis Algorithm Based on Grid Structure in WSN

In wireless sensor network, data information work fault diagnosis can be made by comparison of data from ne sensed by sensor nodes are spatially related, so net- ighbors. Sometimes, transient fault can affect the de- tect accuracy of the network. This paper presents a fault diagnosis algorithm based on grid structure, by which the sensor nodes are identified by comparison of history data from neighboring transient fault. Simulation results indicate that the detection is kept high nodes to avoid the influence affected by the and the energy consumption is reduced.
