Cognitive radio (CR) is proposed to improve frequency efficiency while avoiding interference with licensed users. In this paper, we adopt a resource allocation (RA) algorithm to perform uplink frequency allocation and power control between noncooperative multi-cell for CR network. The proposed RA algorithm is an extension of iterative water-filling algorithm (IWFA) applied to single-cell. The maximization...
A Pareto-efficient, goal-driven, and distributed power control scheme for wireless networks is presented. We use a noncooperative game-theoretic approach to propose a novel pricing scheme that is linearly proportional to the signal-to-interference ratio (SIR) and analytically show that with a proper choice of prices (proportionality constants), the outcome of the noncooperative power control game...
The Stackelberg game is introduced into the power control game, which makes all users in system work in the best equal signal-to-interference (SIR). A new distributed algorithm based on Stackelberg power control game (SPG) is proposed. The simulation results indicate the algorithm can improve the capability of the system. Users receive higher utility and lower transmit power relatively, the use of...
