Özet
In this study, a power management scheme using genetic algorithm optimization method in a heterogeneous LTE network in which there exists femtocells having a low transmission power among macrocells is proposed. The simulation results show that power management for femtocells in the downlink direction plays an important role in reducing the degrading effects of the interference. In the simulations, the results of keeping fixed transmission power of femtocell base stations situation are compared with that of performing optimization case. There is no observable performance loss in the femtocell user's signal-interference and noise ratio due to the power management optimization. On the contrary, almost 50% transmission power decrease of femtocell base station can be provided by means of the proposed power management scheme.
