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%. In this research proposal, we explore new ideas to improve the energy-efficiency of Ethernet passive optical network based fiber-to-the-home/business and hybrid fiber-wireless (FiWi) broadband access networks. The proposed research activities will study the opportunities of power-saving techniques and mechanisms that help save power in both the optical and wireless network domains. Among others, we study coordinated sleep scheduling algorithms for optical network units and wireless access points, data aggregation through network coding, proxying, and selective multipath routing. Toward the realization of a future green video-dominated Internet, we pay particular attention to exploiting the unique traffic characteristics of various types of video applications, e.g., video streaming, to improve the bandwidth-efficient video transport in FiWi access networks. While most of the previous work on "green" communications networks focued on the reduction of their energy consumption and greenhouse gas emissions, we will study the role of energy-efficient access networks in other highly relevant sectors, namely, electricity grids and transport. We explore the opportunities of enhancing FiWi broadband access networks with fiber optic sensors and wireless sensors and adopt them to convert traditional electric power grids, the largest man-created CO2 emission source, into future smart grids.

最近的研究表明，当今互联网的功耗约为典型 OECD 国家电力供应的 0.3% 左右。然而，随着宽带接入在大多数发达国家日益普及，平均接入速率达到 100 Mb/s 时，互联网的功耗预计将上升到国家电力供应的 7% 以上，这相当于每年几太瓦时的电力消耗和数百万美元的费用以及数吨碳气体排放。当前互联网的功耗主要由其第一英里接入网络主导。结果表明，在典型的网络场景中，传输网和核心网约占总功耗的30%，而接入网则占剩余的70%。 在本研究提案中，我们探索了提高基于以太网无源光网络的光纤到户/企业和混合光纤无线（FiWi）宽带接入网络的能源效率的新想法。拟议的研究活动将研究有助于在光和无线网络领域节省电力的节能技术和机制的机会。除此之外，我们研究光网络单元和无线接入点的协调睡眠调度算法，通过网络编码、代理和选择性多路径路由进行数据聚合。为了实现未来以视频为主的绿色互联网，我们特别注重利用各种类型视频应用（例如视频流）的独特流量特征，以提高 FiWi 接入网络中的带宽效率视频传输。虽然之前关于“绿色”通信网络的大部分工作都侧重于减少能源消耗和温室气体排放，但我们将研究节能接入网络在其他高度相关的部门（即电网和运输）中的作用。我们探索利用光纤传感器和无线传感器增强 FiWi 宽带接入网络的机会，并利用它们将传统电网（最大的人造二氧化碳排放源）转变为未来的智能电网。
