A wireless communication device comprising:

• a reception unit configured to receive, by a first channel, a group formation request signal from a management device and a group participation request signal from each of leader devices;
• a mode setting unit configured to set, when the group formation request signal is received, a group formation mode in the wireless communication device during a first duration that is determined in advance;
• a storage configured to receive the group participation request signal from each of the leader devices and store therein a radio field strength at a time of receiving the group participation request signal and an identifier of the leader device that has transmitted the group participation request signal in an associated manner during a period of the group formation mode;
• a selection unit configured to select, when the period of the group formation mode is terminated, the leader device the radio field strength of which, stored in the storage, has a largest value;
• and
• a transmission unit configured to transmit, by a second channel that is different from the first channel, a group participation application signal to the leader device that is selected by the selection unit.
