This project addresses the reduction of energy consumption in optical and wireless access networks via a series of approaches such as capacity-adaptive network design, and energy-efficient resource allocation and traffic scheduling. The capacity-adaptive access network stays in the 'high-capacity high-power' mode when the network is heavily loaded with bandwidth-hungry applications such as video streaming, and switches into the 'low-capacity low-power' mode when the network is lightly loaded with less bandwidth demanding applications such as voice and future smart grid traffic. The project generalizes the approaches currently being used in data centers to communication links, and focuses on formalizing the problem and obtaining optimal or near-optimal solutions. It will not only improve energy efficiency of current access networks, but will also provide insights and guidelines on how to upgrade the capacity of access networks efficiently.The concept of designing capacity-adaptive access networks introduces new requirements of 'capacity adaptive' on the design of access networks as opposed to simply provisioning for peak utilization. This project's energy-aware network control, resource allocation, and traffic scheduling schemes consider an additional key performance metric, energy consumption, in addition to network quality of service, while conventional schemes merely consider network performance such as delay and loss. Research results, via theoretical analysis, simulations, and testbed experiments, will not only demonstrate improved energy efficiency of access networks, but will also be potentially tailored for core networks, datacenter networks, and other wireless systems.Broader Impact:Reducing the energy consumption of access equipment will not only have positive environment impacts during normal operation but it will provide public benefit during emergencies. Remote access equipment is currently powered by a combination of public power, battery backup, and varying degrees of local generation. Techniques such as those being developed by this project that extend operation when on emergency backup help protect the public health and safety. The project will integrate research and education through participation of both undergraduate and graduate students in the project and by incorporation of research outcomes into undergraduate and graduate course work. The PI will utilize the New Jersey Educational Opportunity Program (EOP), which provides educational opportunities to under-represented populations, as part of the process for recruiting students into the research program.

该项目通过一系列方法，如容量自适应网络设计，以及节能的资源分配和流量调度，解决了光和无线接入网络中的能耗降低问题。 容量自适应接入网络在网络重负载有诸如视频流之类的带宽需求大的应用时保持在“高容量高功率”模式，并且在网络轻负载有诸如语音和未来智能电网业务之类的带宽需求较小的应用时切换到“低容量低功率”模式。 该项目将目前在数据中心中使用的方法推广到通信链路，并专注于将问题形式化并获得最佳或接近最佳的解决方案。 它不仅可以提高现有接入网络的能源效率，而且还可以为如何有效地提升接入网络的容量提供见解和指导。设计容量自适应接入网络的概念在接入网络的设计上引入了“容量自适应”的新要求，而不是简单地提供峰值利用率。该项目的能量感知网络控制、资源分配和流量调度方案除了考虑网络服务质量之外，还考虑了一个额外的关键性能指标，即能量消耗，而传统方案仅考虑网络性能，如延迟和丢失。通过理论分析、仿真和测试平台实验，研究结果不仅可以证明接入网的能效得到了提高，而且还可以为核心网、数据中心网和其他无线系统量身定制。更广泛的影响：降低接入设备的能耗不仅可以在正常运行时产生积极的环境影响，还可以在紧急情况下提供公共利益。 远程访问设备目前由公共电源、备用电池和不同程度的本地发电的组合供电。 该项目正在开发的技术，在紧急备用时延长操作时间，有助于保护公众健康和安全。 该项目将通过本科生和研究生参与该项目以及将研究成果纳入本科生和研究生课程工作来整合研究和教育。 PI将利用新泽西教育机会计划（EOP），该计划为代表性不足的人群提供教育机会，作为招募学生参加研究计划的过程的一部分。
