<P>PROBLEM TO BE SOLVED: To provide an ad-hoc network system for extending an operation time by suppressing power consumption, and increasing communication speed by increasing transmission power only in communication requiring a real-time property. <P>SOLUTION: In this ad-hoc network system, each of a plurality of communication terminals is provided with: a search packet generation part 50 for gathering information related to other communication terminals; a transmission/reception part 20 having a setting function of a transmission power value, and transmitting and receiving search packets; a network topology analysis part 30 gathering information related to the other communication terminals based on the search packets received from the other communication terminals by the transmission/reception part 20; a GPS 70 acquiring its own positional information based on the GPS; and a transmission power determination part 40 generating a transmission power value data based on the information related to the other communication terminals, the transmission power value set in the transmission/reception part 20, and the own positional information. The transmission/reception part 20 updates the set transmission power value based on the transmission power value data. <P>COPYRIGHT: (C)2009,JPO&INPIT |
