Abstract:
1. A wireless communication device that performs communication, in a route via a neighbor wireless communication device, with another wireless communication device that exists outside a wireless communication range of the wireless communication device, comprising: an antenna; a set-F table for holding, as unidentified-device identification information, information used to identify an unidentified device that is another wireless communication device to which the reachability of a signal transmitted by the antenna has not been verified; a Multi-Point Relay (MPR) table for holding information used to identify a relay device that is another wireless communication device that relays a signal transmitted by the antenna; and a MPR setting unit for treating, as first destination stations, other wireless communication devices that exist within a wireless communication range of the wireless communication device, treating, as second destination stations, other wireless communication devices that exist outside the wireless communication range of the wireless communication device and within wireless communication ranges of the first destination stations, selecting at least one of the first destination stations as the relay device in accordance with communication states between the wireless communication device and the first destination stations and communication states between the first destination stations and the second destination stations, holding information used to identify the selected relay device in the MPR table, and deleting information used to identify a wireless communication device whose reachability has been verified via the selected relay device from the set-F table, until the unidentified-device identification information held in the set-F table becomes nonexistent.
