A Distributed Wake-up Scheduling Algorithm for Base Stations in Green Cellular Networks

Recently, designing energy-efficient techniques in cellular com-munication has got immense research interest around the world. In this paper, we focus on energy-efficient operation of base transceiver stations (BTSs) in cellular network. We present a distributed wake-up scheduling algorithm (DWS) for the BTSs that use three different modes of operation: off, sleep and active. In DWS, a BTS dynamically takes decision on its operation mode according to the measured traffic load of itself and its neighborhood BTSs in a distributed man-ner. Our simulation results show that the DWS can save as much as 28 % more energy compared to a state-of-the-art Eco-Inspired [6] algorithm
