3G蜂窝基础设施中的基站(BS)网络消耗的能量与其承载的业务负载不成比例。我们的测量表明，3G业务在时间和空间上都表现出很大的波动，从而导致了能量浪费。在这篇文章中，我们提出了绿色基站网络(GreenBSN)来近似全网的能量比例，使用非负载自适应BSES。该工具是一种流量驱动型方法。通过利用固有的时空流量动态和节点部署的异构性，我们在轻流量下关闭未被充分利用的BES。我们对四个地区3G网络的评估显示，GreenBSN在人口密集的大城市节省高达53%的能源，在部署稀少的地区节省23%的能源。
Base station (BS) networks in 3G cellular infrastructure do not consume energy in proportion to their carried traffic load. Our measurements show that the 3G traffic exhibits high fluctuations both in time and over space, thus incurring energy waste. In this paper, we propose Green base station networks (GreenBSN) to approximate network-wide energy proportionality using non-loadadaptive BSes. The instrument is a traffic-driven approach. By leveraging the inherent temporal-spatial traffic dynamics and node deployment heterogeneity, we power off under-utilized BSes under light traffic. Our evaluation on four regional 3G networks shows that GreenBSN yields up to 53 percent energy savings in dense large cities and 23 percent in sparsely deployed regions.
