A system that manages associations of devices with a piconet is provided. The system includes a piconet-device association coordinator, which receives, from a first device, a second association request command that indicates a proper allocation of a device ID to the first device, sets an association elapsed period of the first device to an initial value, and registers the first device and records the association elapsed period to an association device list so that the first device corresponds to the association elapsed period; and a piconet-device associator, which updates an association device list of the first device by referring to the association device list, extracts an association elapsed period of a second device registered on the updated association device list from the updated association device list when the first device requests communication with the second device, and performs the communication between the first and second devices if the extracted association elapsed period is shorter than an association timeout period.
