PROBLEM TO BE SOLVED: To enable secure mutual communication by connection to an identical ad hoc network if an ad hoc network connection is started simultaneously from two or more radio communication devices with an identical radio parameter.SOLUTION: At the start of radio communication, a first radio communication device searches for the surroundings, and forms an ad hoc network if equipment of an identical radio setting does not exist. A radio communication device other than the first radio communication device searches for an opposite party of connection at the start of radio communication, and forms an ad hoc network if the opposite party is discovered, or repeats the search if the opposite party is not discovered until the opposite party is discovered. Thus, in a radio communication device other than one preset radio communication device, the search is repeated until an ad hoc network desired for connection is detected, and participation in the ad hoc network is performed only when detected. |
