Summary:PURPOSE: A data transmission method of a sensor network is provided to prevent data collision between transmission nodes. CONSTITUTION: Transmission nodes respectively create transmission data(S10). The transmission nodes respectively transmit the header parts of the created data to a reception node(S30). The transmission nodes receive a GNM(Grant Notification Message) for selecting one of the transmission nodes from the reception node. According to the GNM message, the transmission nodes transmit the payload part of the created data or converts into a sleep mode without data transmission(S50).
