Femto cell plays major role in the modern wireless communication systems applications. Femto cell provides higher data rates with a tiny base station. The prime concern in femto cell is power allocations for mobile receiver due to interferences. There is a need to develop a suitable power allocation algorithm to improve performance of femto cells. In this paper, an optimized power algorithm Distributive Power Control with Active Link Protection (DPC /ALP) is implemented. The proposed algorithm is tested under MATLAB simulated Long Term Evolution (LTE) environment and also evaluated with existing power allocation techniques i.e. fixed power scheme and power adaptive SINR. It is found that 39 % improvement of power optimization is obtained when compared to the other techniques. The outcome of this research work would be immensely useful for developing robust power optimization techniques for femto cells
