Abstract
Provided is a method for transferring data of a sensor network system in which communication is made with multiple sensor nodes SN1s connected via a wireless network to transmit sensing data measured by the sensor nodes SN1s to a server SNS connected via a wired network. The method includes: receiving the sensing data from each of the sensor nodes SN1s (S1); adding meaning information that corresponds to a measurement value contained in the sensing data to the sensing data (S2, S5); and transmitting the sensing data to which the meaning information is added to the server SNS (S6). Accordingly, data of the sensor nodes are efficiently used by multiple applications while effectively using a reduced resource for wireless communication.
