<p><P>PROBLEM TO BE SOLVED: To provide a wireless network system which builds up autonomously and can achieve the high throughput stably. <P>SOLUTION: A terminal device 1 detects the longitude and latitude of itself and also acquires the longitudes and latitudes of other terminal devices 2, 4, 5, and 8 existing around itself. Then, the terminal device 1 detects the positions of all the terminal devices 1-5 and 8 based on the longitude and latitude of itself and the longitudes and latitudes of the terminal devices 2, 4, 5, and 8, and finds out the distances n1-n4 and D1-D4 based on the detected positions. Furthermore, the terminal device 1 detects the intensity RSSI of a received signal in wireless communication among the terminal devices 2, 4, 5, and 8, and finds a total metric which shows a degree of stabilization of paths from the terminal device 1 to the terminal device 3 based on the detected intensity RSSI of the received signal and the distances n1+D1, n2+D2, n3+D3, and n4+D4. Then, the path for which the total metric becomes minimum is determined as a path from the terminal device 1 to the terminal device 3. <P>COPYRIGHT: (C)2007,JPO&INPIT</p> |
