Increased environmental awareness coupled with the rising cost of energy have sparked a keen interest in the deployment
of energy-efficient communication technologies over the infrastructure of cellular networks. Base stations (BSs) are responsible for the
largest portion of power consumption and energy usage in cellular networks. Thus, sleep/wake-up scheduling strategies for BSs can
significantly improve energy-efficiency (EE) of cellular networks. In this paper, we propose a Fuzzy Q-Learning (FQL) based energy-efficient
sleep/wake-up mechanism for BSs in a heterogeneous network (HetNet). The goal is to save energy, without compromising
the offered Quality of Service (QoS), by switching off the redundant BSs according to the local traffic profile and depending on the
required area coverage and cell EE. The introduction of sleep mode for BSs may lead to a large-scale coverage loss, unless a specific
remedial solution is exploited at the same time. To this end, we also propose to use device-to-device (D2D) communications to extend
network coverage to the service areas of the switched-off BSs. Simulation results validate that the proposed framework provides significant
improvements in power consumption and the EE. |
