ZigBee network nodes in the great scale of data communication,communication does not agree for time domain by the conflict is put forward based on triangle calibration collision prediction of the channel conflict put signal mechanism.The same node of communication of the signal more than a signal virtual calibration area is used.Through the establishment of the wireless sensor signal collision detection model conflict time domain is prediction of communication conflict judgment.Through the time domain signals of 2 d regional collision forecast,the collision of the may probability is calculatied.The experimental results show that the method can be used to big data,to node,long ZigBee communication network communication optimization.The efficiency of the node channel communications is improved.At the same time,this method greatly reduces the wireless communication network data of the collision of the possibilities.
