Abstract :
In this paper, we study how to deploy different kinds of base stations (BSs) in green cellular networks. Unlike previous studies which deploy BSs only based on the peak traffic load, we propose an optimal deployment scheme to minimize the total power consumption over time and spatial domain based on the traffic variation characteristics. Our method can be decomposed of two steps: how to achieve limit suboptimal deployment scheme according to peak rate and how to operate BSs on/off in low load for the given deployment. A greedy heuristic deployment algorithm is proposed to additionally deploy micro BSs and separately replace macro BS. Simulations based on the regular BS topologies and real traffic profiles show that the proposed algorithms can significantly reduce the energy consumption.
