METHOD OF AVOIDING INTERFERENCE AND RECLUSTERING METHOD OF CLUSTERED WIRELESS SENSOR NETWORKS AND WIRELESS SENSOR COMMUNICATION APPARATUS APPLIED THERETO

摘要

PURPOSE: A method of avoiding interference and a reconstitution method of clustered wireless sensor networks and a wireless sensor communication device applied thereof are provided to remove the terminal node which cannot transfer sensing data by external interference. CONSTITUTION: A sensor network communication device detects a cluster head of the environment of a terminal node(S402). The device waits a Beacon response(S403). The device determines a cluster head which is closest to the terminal node thruobh the response of the cluster head if the channel scan is completed(S404,S405). A terminal node sends a connection request message to the determined cluster head(S406). The terminal node communicates with the new cluster head(S408).
