Abstract
With the continuous development of information, wireless network has become an integral part of people’s everyday lives. With the explosive growth of data in wireless network, the interferences and competition for resources are more and more serious, especially in the intensive network scenarios. Power control can effectively reduce the interference to improve throughput, save energy and prolong the service life of equipment. This paper proposes a power optimization strategy for Femtocell base station in LTE-A, a two-tier network. It plans the problem into Stackelberg Game, as Stackelberg Game model well describes the user behaviors, making it an effective analysis tool. Then this paper researches the Stackelberg equilibrium and obtains the optimal power distribution and optimal power pricing method. Based on it, a distributed non-uniform pricing algorithm, DNP, is proposed for Femtocell base station deployment. It realizes the distributed deployment with low complexity and less information interaction, and also shows a good performance through simulation, thus having a guiding significance for the power control scheme of Femtocell base station deployment.
