SENSOR NETWORK SYSTEM AND METHOD FOR CONTROLLING THEREOF

摘要

PURPOSE: A sensor network system and control method thereof are provided to communicate between sensor nodes by using minimum RF(Radio Frequency) strength which is necessary for communication by calculating the minimum RF strength. CONSTITUTION: A source sensor node creates a loopback test request message according to the occurrence of previously established events. The source sensor node transmits the loop-back test request message to a destination sensor node(S100). The source sensor node receives a loopback test response message from the destination sensor node(S200). The source sensor node establishes RF(Radio Frequency) gain values of a wireless communication module within the source sensor node based on analysis results of the received loopback test response message.
