Mobile communications witness an exponential growth of data traffic. as a consequence, the energy consumption of cellular networks is increasing fast which make the operating expenditures more challenging for operators. Large scale efforts are done for improving the energy-saving technologies at system level.

Current base stations consume 60-80% of the whole cellular network energy consumption. Thus, deployment of small-cells (micro, pico, femto) based on low-power are a promising technology in order to respond the continuous growth of traffic demand. However, dramatic densification of micro-cells leads to the multiplication of energy consumed by the radio access network.

In this context, different approaches has been studied in literature, mainly the switch on/off of Base stations. Hence, the current work aims to suggest strategies for optimizing the energy consumption in micro-cell LTE infrastructure under coverage and quality of service constraints.
