The wireless revolution requires future wireless networks the capability of intelligently optimizing the spectrum by collaborating with, and learning from, the other systems that occupy the same spectrum bands. How to develop the wireless paradigm of col-laborative, therefore, is a crucial question. In this paper, we discuss how to model the collaborative power control in a wireless interference network, where users share the same frequency band. By collaborating with other users, each user exchanges information to maximize not only its own performance but also others' performances. A game theory framework is developed to determine the optimal power allocation. The proposed framework possesses several advantages over conventional methods, such as low-complexity and fast-converging algorithmic solution, distributed implementation and better user fairness. Simulation results state the proposed approach provides better fairness between users' data rates, higher performance in the aggregate rate and lower convergence time.
