  The energy efficiency aspect of cellular networks is a vital topic of
research over the recent days. As energy consumption is on the rise and the
price of electricity is increasing very rapidly, necessity to reduce
electricity usage in every aspect is becoming much more significant. The power
grid infrastructure, from which the cellular networks attain the required
electricity for operation is considering a significant change from the
traditional electricity grid to the smart grid. The base stations, which are
the main candidates for energy consumption in cellular networks, remain in
operation even when there are a very few users or no user at all. In this
paper, we propose an effective application scenario of the femtocell technology
for power saving purpose of cellular networks. Effective deployment of
femto-access-points in the required places can reduce the power usage of
cellular networks by turning off the redundant base stations. Moreover, the
signal to noise plus interference ratio is also enhanced in comparison to the
traditional scheme. The base station turn off probability and the energy
consumption in the overall network are analyzed. The comparison results show
that the proposed energy efficient model can significantly reduce energy
consumption and increase the service quality of the cellular users.
