Current research in base station(BS) energy consumption area is mostly devoted to the study of the static energy consumption or dynamic factor. But it lacks the research on the energy storage efficiency of the BS. In this paper, we propose a power modeling of BSs based on energy storage monitoring. Firstly, the system architecture and networking scheme of energy storage monitoring are presented, and...
This paper focuses on D2D clustering communication method in the uplink and downlink aiming at saving energy of Mobile Terminals (MTs). The method contains MTs clustering method and cluster head selection methods. The MTs clustering method is based on the distance information of MTs. The cluster head selection method is based on the energy consumption or the residual energy of MTs. And Quality of...
Energy efficiency in future green cellular wireless networks poses a challenge to operators and researchers. An effective method of providing energy savings (ES) in base stations (BSs) is to switch off idle BSs or put them into sleep mode and subsequently migrate the traffic loads to active BSs in their neighborhood. The intrinsic issue related to such methods applied to heterogeneous networks (HetNets)...
Power models are crucial to assess the power consumption of base stations (BSs) without quantitive description. Currently available models seldom consider the dynamic factors such as indoor and outdoor temperature. As power model will affect the energy-saving gains of different green resolutions, in this paper we provide such power models for mobile communication BSs relying on practical data collected...
Aiming to resolve insufficiency of existing Energy-Saving (ES) methods in heterogeneous network, a novel self-organizing ES mechanism to improve energy efficiency suitable for heterogeneous networks is proposed. In the mechanism, we come up with the self-organizing procedures, the traffic model, and an optimizing objective model. The mechanism is then simulated under an urban LTE scenario with 7 macro...
For the sake of the increase of energy consumption, the emission of carbide can't be negligible. In this paper, we propose a mathematical model which adjusts the radius of base station, to figure out the problem of energy saving, while the quality of services such as the traffic volume of each base station and the service area should be satisfied. For the model, we use ant colony algorithm as a practical...
When regional traffic is low, one key issue of ESM (Energy-Saving Management) in cellular networks is how to sleep several BSs (Base Stations) and meanwhile guaranteeing regional coverage and service quality. Current ESM methods lack efficient regional coverage compensation method and accurate evaluation model for ESM algorithms. This paper proposes a novel ESM mechanism to resolve these problems...
