In a method of configuring an ad hoc network system including a plurality of wireless terminals, at least one of a plurality of wireless terminals of a network is selected as a current temporary parent wireless terminal, all of the plurality of wireless terminals other than the current temporary parent wireless terminal being set as child wireless terminals. Subsequently, a set of state determination data are collected from each of the child wireless terminals by the current temporary parent wireless terminal. The state determination data includes at least one of a wireless terminal state data of each of the child wireless terminals and a communication state data with each of the child wireless terminals. Then, it is determined whether the collecting operation is executed K cycles (K is a positive integer).
