<P>PROBLEM TO BE SOLVED: To provide a wireless communication system that allows a parent node to communicate with a specific child node with priority and that is able to suppress deterioration of system throughput. <P>SOLUTION: When data addressed to child nodes 22A, 24A, and 26A are received from child nodes 21A, 23A, and 25A, a parent node 1A transmits the data addressed to the child nodes 22A, 24A, and 26A using a super frame SF2a, which is formed by a beacon signal slot TS4 for transmitting a beacon signal including specific terminal information as information about the child nodes 22A, 24A, and 26A, and a specific terminal corresponding slot TS5 following the beacon signal slot TS4 for communicating in an interactive manner with at least the child nodes 22A, 24A, and 26A, and sets a time length of the specific terminal corresponding slot TS5 to be the shortest time enabling transmission of the data addressed to the child nodes 22A, 24A, and 26A. <P>COPYRIGHT: (C)2012,JPO&INPIT |
