Energy-aware heterogeneous access and sensor networks

最近的研究表明，当今互联网的耗电量约为一个典型经合组织国家电力供应的0.3%。然而，随着宽带接入在大多数发达国家日益普及，据估计，平均接入速率上升到100mb /s，互联网的电力消耗将上升到一个国家全国电力供应的7%以上，这意味着每年消耗几太瓦时的电力，数百万美元的费用和吨的碳气体排放。当前互联网的电力消耗主要由第一英里接入网控制。研究表明，在典型的网络场景中，传输网和核心网约占总功耗的30%，接入网约占70%。

Recent studies show that the power consumption of today's Internet is around 0.3% of the electricity supply of a typical OECD country. However, as broadband access becomes increasingly commonplace in most developed countries, the power consumption of the Internet is estimated to rise to more than 7% of a country's national electricity supply for an average access rate rising to 100 Mb/s, which translates into a power consumption of several TWh and expenses of millions of dollars and tons of carbon gas emissions per year. The power consumption of the current Internet is largely dominated by its first-mile access networks. It was shown that in a typical network scenario, transport and core networks represent roughly 30% of the total power consumption, while access networks account for the remaining 70%.
