Provided is a management device maintaining communication qualities while accommodating a changeable communication environment. Based on correspondence between each geographical position of plural managed devices and available frequencies thereat, pair available frequencies available in common by arbitrary two managed devices are specified for each pair, and notified to the arbitrary two devices. From managed devices, acquiring pair communication qualities obtained when the pair available frequencies is used, defined is a best pair available frequency capable of obtaining a best pair communication quality. Specifying all of candidate paths connecting the each pair, relaying other managed devices, calculated are, based on the best pair communication quality, path communication qualities in the candidate paths connecting the each pair using the best pair available frequency. Selecting for the each pair a use path having a best quality in the path communication qualities, communication between the each pair is performed by using the use path. |
