ENHANCED TRANSMISSION ENERGY EFFICIENCY IN AN LTE HETEROGENEOUS NETWORK USING ADAPTIVE CELL SELECTION ALGORITHM

This paper presents enhance transmission energy efficiency in an LTE heterogeneous network using adaptive cell selection algorithm. This was embarked on to maintain quality of service which has not been achieved constantly in the existing system. The problem was addressed developing an adaptive cell selection algorithm which ensured that when the signal strength of a cell is below standard, the cell handover neighbouring one which has better performance. This algorithm was implemented with Simulink and evaluated. The result showed that the signal strength was maintained from at -90.16dB as against -105.8 in characterized. The implication o this result when analysed with the ITU-T standard showed that the quality of service in the network with adaptive cell selection algorithm was maintained with 10.5% energy conservation improvement and energy efficiency achieved is 54%.
