PURPOSE: A method for transmitting a message data in wireless sensor network with minimum energy is provided to reduce energy consumption for data transmission by transmitting data through a selected transmission sensor node. CONSTITUTION: A plurality of sensor nodes calculates a selected parameter(S1). A header node receives sensed data of the sensor node and the selected parameter from sensor nodes(S3). The header node generates the collection data(S4). The header node selects the transmission sensor node for the transmission of collection data(S5). The header node generates the selection signal for the transmission control of collection data(S7). The header node transmits the selection signal and collection data to sensor nodes in a broadcasting type(S9). |
