Femtocell is one of the promising solutions that can improve the energy efficiency of cellular network. However, densely and randomly deployed femtocells may experience server inter-femtocell interference due to rough-and-tumble spectrum reuse with unconstrained power. In this paper, the downlink power control problem is investigated to achieve an energy efficient power allocation scheme. The problem is formulated as a non-cooperative game and distributed power control algorithm is proposed. Numerical results suggest that a good energy efficiency improvement is acquired and the algorithm converge within a few iteration times.
