Abstract:
1. A wireless-communication device configured to communicate with a first different wireless-communication device provided outside a wireless-communication range through a path via a neighbor wireless-communication device, the wireless-communication device comprising: first identification-information-storage means configured to store information corresponding to at least one first opposite station existing inside a first wireless-communication range of the device itself; second identification-information-storage means configured to store information corresponding to at least one second opposite station existing inside a second wireless-communication range of the first opposite station and existing outside the first wireless-communication range; broadcast-signal-generation means configured to generate a broadcast signal and transmit the generated broadcast signal to at least one second different wireless-communication device, where the broadcast signal includes a propagation-node number data calculated by subtracting a total number of a number of nodes of the first opposite station and a number of nodes of the second opposite station from a threshold value of the propagation-node number; and broadcast-signal-transfer means configured to set the transfer-finish-instruction signal for finishing transferring the broadcast signal if the propagation-node number data included in the broadcast signal is smaller than a number calculated by subtracting a number of the nodes of the second opposite station existing inside the second wireless-communication range of the first opposite station that transmitted the broadcast signal from the number of the nodes of the at least one second opposite station, and configured to set a number obtained by subtracting the number obtained by subtracting the number of the nodes of the second opposite station existing inside the second wireless-communication range of the first opposite station that transmitted the broadcast signal from the number of the nodes of the second opposite station from the propagation-node number data of the broadcast signal, as another propagation-node number data, and transfer the broadcast signal to at least a different wireless communication device when the transfer-finish-instruction signal of the broadcast signal transmitted from any of the at least one first opposite station does not instruct to finish transferring the broadcast signal.
