A Fault Diagnosis Algorithm Based on Grid Structure in WSN
Liu Ha · Electronic Science and Technology · 2014
In wireless sensor network,data information sensed by sensor nodes are spatially related,so network fault diagnosis can be made by comparison of data from neighbors. Sometimes,transient fault can affect the detect 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 nodes to avoid the influence affected by the transient fault. Simulation results indicate that the detection is kept high and the energy consumption is reduced.
