Base Station Switch off Methods for Mobile Communication without Effecting QoS

During low traffic hours switching off the base stations is an effective way of saving energy in mobile communication network. To serve increased traffic and to fulfill large and high speed data demand, operators are deploying more number off base stations. This is leading to more energy consumption in the mobile communication network. So minimizing the energy consumption in the mobile communication has become a primary concern. In communication system maximum energy is consumed at the base stations. Hence by switching off some of the base stations at low traffic hours, energy can be saved. In this work we developed static and dynamic base station switch off methods to minimize the energy consumption during low traffic condition. Using this base station switch off methods we are able to save 12.63%, 10.81% and 12.66% of power for three different traffic scenarios.
