Cell Zooming for Energy Efficient Wireless Cellular Network

The dynamic growth of Information and Communication Technology (ICT) have considerably increased the energy requirements and also contribute a growing fraction to CO2 emissions, thereby creating a need for wireless communications to be more energy-efficient. In this paper, Cell Zooming concept isimplementedforreducingtheoverallpowerconsumptionofthenetworkfor a five cell microcellular network adopting SON technique. When the traffic load is low in central base station, it could be switched off while its users are given coverage by cell zooming the neighboring cells. Simulation results indicate that by using the Cell Zooming concept, nearly 20% of the overall power consumption of the network can be reduced. This would herald the emergence of the Green Base Station in Wireless Cellular Network.
