Wireless network system and wireless communication program
First Claim
1. A wireless network system composed of a plurality of terminal devices having a radio communication function, one of the plurality of terminal devices acting as a master device for controlling data transfer timing in a network, each terminal device other than the master device acting as a slave device performing data transfer with the master device under control of the master device, wherein each of the plurality of terminal devices includes:
- a master device search section for searching for any other terminal device acting as the master device or a temporary master device;
a temporary master process section for causing the terminal device itself to act as the temporary master device;
a switching section for, if no network is constructed with any other terminal device, performing a switching operation for alternately activating the master device search section and the temporary master process section;
a slave process section for, if the master device search section detects presence of the master device or temporary master device, causing the terminal device itself to act as a slave device for the detected master device or temporary master device; and
a master process section for, if another terminal device is detected as searching for the master device or temporary master device during a period for which the terminal device itself is caused by the temporary master process section to act as the temporary master device, causing the terminal device itself to act as the master device.

Abstract
Upon receipt of a network connection request, a CPU core of a game device randomly sets a master device search period, and searches for a master device or a temporary master device until the master device search period ends. When the master device search period ends, the CPU core randomly sets a temporary master process period, and causes the game device to act as a temporary master until the temporary master process period ends. The CPU core alternately repeats the master device search and the temporary master process. The game device is caused to act as a slave device if any game device acting as the master device or temporary master device is found during the master device search period. Alternatively, the game device is caused to act as a master device if a connection request from another game device is received during the temporary master process period. Thus, it is possible to automatically construct a wireless network with one master device and one or more slave devices.

11. A computer-readable storage medium having stored therein a radio communication program for constructing a wireless network system composed of a plurality of terminal devices having a radio communication function, one of the plurality of terminal devices acting as a master device for controlling data transfer timing in a network, each terminal device other than the master device acting as a slave device performing data transfer with the master device under control of the master device, wherein
the radio communication program causes a computer of a terminal device to act as: -
a master device search section for searching for any other terminal device acting as the master device or a temporary master device;
a temporary master process section for causing the terminal device itself to act as the temporary master device;
a switching section for, if no network is constructed with any other terminal device, performing a switching operation for alternately activating the master device search section and the temporary master process section;
a slave process section for, if the master device search section detects presence of the master device or temporary master device, causing the terminal device itself to act as a slave device for the detected master device or temporary master device; and
a master process section for, if another terminal device is detected as searching for the master device or temporary master device during a period for which the terminal device itself is caused by the temporary master process section to act as the temporary master device, causing the terminal device itself to act as the master device. - View Dependent Claims (12, 13, 14, 15, 16, 17, 18, 19, 20)
