1. A controller apparatus configured to control an ad hoc network formed by a plurality of mobile terminals, and provided in an assist network separate from the ad hoc network, the controller apparatus comprising:
- a storage unit configured to store traffic distribution information indicating a traffic distribution in the ad hoc network which is a correspondence between traffic volume of respective mobile terminals and locations of the respective mobile terminals, the traffic volume being any one of a volume of packets actually transmitted, a volume of packets actually received and a volume of packets stored in a transmission buffer of each of the respective mobile terminals; and
a transmission power determining unit configured to determine transmission power of a mobile terminal joining in the ad hoc network, based on the stored traffic distribution information,wherein the controller apparatus receives the traffic volume and the locations from the respective mobile terminals via the assist network, andthe controller apparatus transmits the determined transmission power to the mobile terminal joining in the ad hoc network via the assist network.
