Wireless communication device, wireless communication system, and computer program product

A wireless communication system comprising:

• a plurality of wireless communication devices constituting a wireless multi-hop network, the wireless communication devices each including one or more hardware processors configured to:
• collect forwarding load information about wireless communications in the wireless multi-hop network;
• determine whether to be a packet corresponds to a forwarding determination target;
• determine, based on the forwarding load information, a degree of forwarding priority for the packet corresponding to the forwarding determination target;
• and,
• when the packet corresponding to the forwarding determination target is forwarded, transmit the packet corresponding to the forwarding determination target by multi-cast communications or broadcast communications;
• count, for a predetermined period of time, a packet transmission count in the wireless communication device to collect the packet transmission count as the forwarding load information;
• and
• determine to lower the degree of forwarding priority as the packet transmission count is greater.

A computer program product comprising a non-transitory computer-readable recording medium on which an executable program is recorded, the program instructing a computer to:

• collect forwarding load information about wireless communications in a wireless multi-hop network;
• determine whether to be a packet corresponds to a forwarding determination target;
• determine, based on the forwarding load information, a degree of forwarding priority for the packet corresponding to the forwarding determination target;
• and,
• when the packet corresponding to the forwarding determination target is forwarded, transmit the packet corresponding to the forwarding determination target by multi-cast communications or broadcast communications;
• count, for a predetermined period of time, a packet transmission count in the wireless communication device to collect the packet transmission count as the forwarding load information;
• and
• determine to lower the degree of forwarding priority as the packet transmission count is greater.
