<P>PROBLEM TO BE SOLVED: To provide a wireless network system with a plurality of nodes sharing frequency hopping patterns. <P>SOLUTION: A channel list table is provided including a channel list including a state of channels of the shared frequency hopping pattern including the channel which can be used for communication with a target node regarding respective transmission nodes. Then, a channel for the next allotted time slot is selected from the shared frequency hopping patterns and a channel list for the target node which is the transmission destination is selected from the channel list table. Next, whether or not the selected channel can be used is checked based on the selected channel list. The selected channel is set when the selected channel can be used. When the selected channel cannot be used, an alternative channel is calculated from the channel list instead of the selected channel. <P>COPYRIGHT: (C)2012,JPO&INPIT |
