Apparatus and method for network controlling in wireless communication system

PURPOSE: A network construction apparatus in a wireless communication system and method thereof are provided to construct a network between terminals by reducing unnecessary connection by considering of the probability distribution of the terminals in the wireless communication system. CONSTITUTION: A terminal constitutes an external and an internal domain based on a standard terminal(209). Power for communicating with the external neighbor terminal and the internal neighbor terminal is confirmed(213). In case an ACK(Acknowledgement) message is transmitted for standard messages received from the adjacent terminal, the terminal confirms transmission power for the transmission of the ACK message(215,217). The terminal determines maximum transmission power as final transmission power for constituting of a network(219).
