The invention provides a controller apparatus for performing communication control of traffic distribution changed with time, based on a weighing relationship between the throughput in a whole self-organization network and the communication relay time in mobile terminals. The controller apparatus (10) is configured to control an ad hoc network formed by a plurality of mobile terminals. The controller apparatus (10) includes a transmission power determining unit (16) configured to determine transmission power of a certain mobile terminal joining in the ad hoc network, based on traffic distribution in an ad hoc network.
