SINK NODE AND ITS OPERATING METHOD

摘要

PURPOSE: A sink node and an operating method thereof are provided to classify detection values in effective ranges by judging the validity of the detected value of each sensor node. CONSTITUTION: A sensor node(100) detects the peripheral information periodically, and transmits a detection value to a sync node(110). A wired/wireless communication unit(112) performs the communication with the sensor node or a cluster head node and a host. For the detection value, a detection value management unit(114) process the detection value according to first and second threshold values for each preset sensor node. A detection value storage unit(116) generates the detection value for each unit time in record.
