Communication device, communication method, and recording medium

A communication device that uses wireless channels, the communication device comprising:

• an acceptance unit accepting, from a different communication device and through one of the wireless channels, channel information that indicates wireless channels that can be used by the different communication device;
• a control unit, when forwarding information, which is provided with transmission channel information indicating a wireless transmission channel used by a transmission source, is received through one of the wireless channels, selecting, as a wireless forwarding channel to be used to forward the forwarding information, a wireless channel that is different from the wireless transmission channel from among the wireless channels of the device, based on the wireless channels indicated by the channel information;
• and
• a transmission unit forwarding the forwarding information to a forwarding destination by using the wireless forwarding channel.

A communication method in a communication device that uses wireless channels, the communication method comprising:

• accepting, from a different communication device and through one of the wireless channels, channel information that indicates wireless channels that can be used by the different communication device;
• selecting, as a wireless forwarding channel for first information, a wireless channel, which is different from a wireless transmission channel for transmitting the first information, from among the wireless channels that are indicated by the channel information, and adding second information that indicates the wireless forwarding channel to the first information;
• and
• transmitting the first information provided with the second information by using the wireless transmission channel.
