<p><P>PROBLEM TO BE SOLVED: To perform more appropriate radio communication in a radio network operating by means of multiple radio modes. <P>SOLUTION: Radio terminal devices 102-109 constitute a network allowing communication with a neighboring radio terminal device by means of different radio modes. Each terminal device includes a state management unit 250 which calculates a cost for each radio mode of a neighboring radio terminal device based on a path cost determined for each path from a coordinator 101 to the neighboring radio terminal device and a link cost determined for each different radio mode, and according to the calculated cost, selects a neighboring radio terminal device of the radio mode used for transmission and reception. <P>COPYRIGHT: (C)2013,JPO&INPIT</p> |
