Abstract

This paper, we investigates the energy efficiency optimization problem in SFR-based cellular networks. To the end, we uses divide-and-conquer method to improve network energy efficiency. We build an optimization model with an objective function denoting energy efficiency of networks, which is a fractional program and very hard to be solved directly. To solve the model, we transform the objective function into another form. Then we utilize the Lagrange function and dual function to obtain the optimal energy efficiency with the gradient method updating the transmitting power allocation. Finally, we make a numerical simulation to validate the algorithm proposed. The simulation results show that the performance of our method is feasible.
