Small cells have been increasingly deployed over the coverage provided by macro base stations (BSs) to satisfy the capacity demand at high traffic areas, adding to the costs in energy consumption for running the network. This paper provides a solution for dynamically switching the operation modes of small cells between idle and active according to the traffic variation of network exploiting the distinct characteristics of power consumption models of various BSs to achieve energy saving (ES) gains without compromising the quality of service (QoS) to network users. The validity and effectiveness of the proposed solution have been evaluated through extensive simulation results based on a sophisticated network simulator built in-house, which features realistic scenario setting, spatially and temporally varying traffic emulation, reasonable network planning and a variety of practical network performance metrics.
