Development of a Hibernation Scheme for Reducing Energy Consumption in a Communication Base Station

This paper “Development of a hibernation scheme for reducing energy consumption in a communication base station” is aimed at reducing energy consumption in communication network base stations considering the rising cost of energy in our country, Nigeria today. The scheme was developed using models that by calculations detects when any of the system components is in inactive mode. Such system component will be switched off to avoid energy wastage. The preliminary energy consumption evaluation carried out identified the power amplifiers as the component that consumes the highest energy at the station and yet it's not all the time active. When the developed scheme was simulated, the results showed that during data transmission process, low noise amplifier (at the receive node) was not all the time active and power of 1250W was conserved. Also, in the receiving end the result showed that the RF power amplifier was in hibernation mode on many occasions and about 950W of power was conserved. The overall power consumed with the hibernation scheme is 5421W and of the evaluated without the scheme is 7321W. The percentage save with the hibernation scheme is 25.9%. The overall objective is to be able to run base stations in Nigeria with small generating plants and reduce also emissions from big generating plants.
