Abstract:

Based on hierarchy noncooperative game theory in open sharing model, a distributed algorithm used for adaptive power control is proposed. The algorithm is composed of outer updating and inner updating, in which each user can implement periodic information interaction and adjust its transmitted power adaptively. Through Simulation verifies that the information interaction can be decreased with the proposed when distributed updating, the nearoptimal solution is obtained at the same time.
