<p><P>PROBLEM TO BE SOLVED: To provide a method of data transmission adapted to make capable of efficiently and surely transmitting data in a wireless network. <P>SOLUTION: A method of data transmission is provided that is designed to select member nodes of relay clusters for data transfer in a wireless network. The wireless network includes one or more relay clusters G1_1to 3 (the clusters for the first relay stage) and G2_1 to 4 (the clusters for the second relay stage), each cluster formed of a group of nodes of the wireless network. In the present method, the data received by the nodes in one of such relay clusters belonging to the wireless network are transferred in synchronization by simultaneous transferring after the group of nodes has received the received data, in which the data transfer is effected in such a way that the nodes in the relay cluster collectively and simultaneously act as relay nodes of the received data. <P>COPYRIGHT: (C)2010,JPO&INPIT</p> |
