<P>PROBLEM TO BE SOLVED: To provide a clock time synchronizing method capable of establishing clock time synchronization in a network. <P>SOLUTION: In the method for synchronizing clock times of the network of a tree structure constituted of a plurality of nodes, a parent node leads a clock of the parent node for very carrier sense, generates clock time information on the basis of a lead time, and transmits the clock time information to a child node. The child node performs delay correction of the amount of one hop on the clock time information. By setting the time of the child node, it is possible to establish clock time synchronization in the network. <P>COPYRIGHT: (C)2006,JPO&NCIPI |
