In one wireless device, when wishing to participate in a communications network, an ID generator in an ID manager uses a hash function on the address of the device and time to generate a device identification identifying the one device, and registers the identification on a list storage. In the one wireless device, a list updater stores an identification of another device from a beacon signal into the list storage in association with the address of the other device. When a conflict determiner detects a conflict of device identifications, an ID searcher searches the list storage for an unused identification having a relationship with the conflicting identification according to a relation in magnitude between the addresses of the one and other devices. An ID updater updates the identification of the device in the list storage to the unused identification thus searched for as a new identification.
