Development of low power mobile network has become a promising research area. To give good signal strength at low power transmission femtocell and picocell are developed. But random deployment of these small cells increases the power transmission and the environment gets affected. Moreover interference management becomes difficult. To overcome this problem this paper proposes a congestion control scheme where the cell zooming concept is incorporated in the small cell network. The small cells are activated and their coverage are expanded and shrunk in such a way that the users get good signal level but the net power consumption is reduced. The signal-to-interference-plus-noise-ratio (SINR) in the proposed scheme is determined. The performance of the proposed scheme is experimentally analyzed using vector signal generator and vector signal generator. The mathematical and experimental analyses show that the proposed method reduces the power consumption and improves the SINR than existing macro-pico-femtocell based network.
