To reduce the energy consumption in heterogeneous 5G access networks, we propose a
cooperative energy-saving mechanism based on user association (UA-CESM). Joint …

The exponential increase of wireless services has led to a great amount of energy
consumption of base stations (BSs). In this paper, we envision that BSs of future cellular …

Green communications has received much attention recently. For cellular networks, the base
stations (BSs) account for more than 50 percent of the energy consumption of the networks …

In this paper, we study the problem of energy cost minimization in heterogenous cellular
networks with hybrid energy supplies, where the network architecture consisting of radio …

At present, the energy consumption of wireless communication network accounts for the vast
majority of the operator's expenses. A cooperative energy saving mechanism is proposed in …

Greening information and communications technology is becoming an environmental and
economic sine qua non, and has attracted much research attention. For a cellular network …

Heterogeneous cellular network (HCN), which generally consists of small cell base stations
(SBSs) and macro base stations (MBSs), is proposed as a promising scheme to improve the …

Energy consumption is rising sharply due to the large deployment of the Home Base
Stations (HeNBs) by subscribers, it not only brings the cost burden to operators, but also …

Greening information and communications technology is becoming an environmental and
economic sine qua non, and has attracted much research attention. For a cellular network …

To alleviate the burden on power grid in heterogeneous cellular networks, energy
harvesting (EH) has inspired thorough research in both academia and industry. However …
