Abstract
Provided is a data transmission method of a plurality of sending nodes in a sensor network. In the data transmission method, data is generated to be transmitted to a receiving node, respectively. Headers of the generated data are transmitted to the receiving node, respectively, in response to a Wake-up Notification Message (WNM) from the receiving node. A Grant Notification Message (GNM) for selecting one of the plurality of sending nodes is received from the receiving node. The plurality of sending nodes transmit a payload of the generated data according to the GNM, or switch into sleep mode without data transmission.
