Abstract :
Due to the energy of mobile device is limited, an energy efficient communication protocol is important. In 3GPP LTE-Advanced network, energy consumption can be reduced through discontinuous reception (DRX) mechanism. However, unsuitable DRX parameters may significantly increase packet delay when packets for UE arrive from Internet during DRX period. To deal with the tradeoff between energy consumption and packet delay, a fuzzy logic controller (FLC) is proposed to adaptively adjust DRX cycle. The proposed mechanism includes traffic estimation and fuzzy logic controller. With the predicated traffic amount, FLC-based DRX mechanism can automatically adjust DRX parameters to achieve better tradeoff between energy consumption and packet delay. Numerical results reveal that the proposed adaptive fuzzy adaptive DRX mechanism outperforms fixed DRX parameters.
