Cell zooming for energy efficient cellular networks

`Efficiency' is a booming word in the current global scenario. The paper describes such an algorithm named `cell zooming' that aims at providing energy efficiency to the operating cellular network. Energy efficiency is achieved by operating some selected base stations in sleep mode. The energy consumed in sleep mode is much lesser when compared to the normal operation. Here, the performance analysis for cell zooming is done by comparing a number of channel models; taking into account the practical implications. Cell zooming algorithm helps in attaining a greener environment; besides satisfying all the user needs with appreciable quality of service.
