For the fault-tolerant events'region detection problem of wireless sensor network,an algorithm based on aggregation tree was given.The algorithm builds distributed aggregation tree first,each node reports its own perception of data to the nearest tree node,tree node implementation of multiple linear regression,on single or multiple simultaneous events for fault detection,access to the event area detection estimates.At the same time,aggregation network redundant information and reduce data traffic.Simulation results show that the algorithm has a high error detection accuracy,and can improve the event area boundary node error correction.
