SENSOR NETWORK SYSTEM, GATEWAY NODE, AND METHOD FOR RELAYING DATA OF SENSOR NETWORK SYSTEM

摘要

Provided is a method for transferring data of a sensor network system in which communication is made with multiple sensor nodes SN 1 s connected via a wireless network to transmit sensing data measured by the sensor nodes SN 1 s to a server SNS connected via a wired network. The method includes: receiving the sensing data from each of the sensor nodes SN 1 s (S 1 ); adding meaning information that corresponds to a measurement value contained in the sensing data to the sensing data (S 2 , S 5 ); and transmitting the sensing data to which the meaning information is added to the server SNS (S 6 ). Accordingly, data of the sensor nodes are efficiently used by multiple applications while effectively using a reduced resource for wireless communication.
