The past decade has witnessed an explosive growth of tremendous mobile traffic, pervasive smart devices, and assorted new applications. While this growth leads to increasing revenue for the global mobile industry, there are rising concerns on environmental impact and high capital/operating expenditure. Driven by the pressing needs from both economical and ecological perspectives, energy efficiency and greening becomes one of the dominant themes for 5G wireless networks. Although such demands have attracted considerable attentions and efforts from the academia and industry, the evolving network architectures need to be continuously augmented with green networking algorithms to fully harvest the potentials. Meanwhile, new user-driven applications keep emerging and call for efficient solutions to maintain sustainable growth. This research program will contribute to the evolution towards next-generation green wireless networks through exploring energy-aware techniques that leverage evolving network architectures, smarter mobile devices, and diverse characteristics of a plethora of emerging applications. Particularly, we will focus on three thrusts. First, exploiting the intelligence of smart devices, we will develop new algorithms for cooperation cluster grouping, task assignment, and incentive for user participation. Energy-efficient multipath transport protocols with user cooperation will also be studied by balancing throughput performance and energy consumption. Second, taking advantage of multi-tier radio access networks, we will develop traffic-aware sleep schemes for different types of base stations, and service-differentiated scheduling schemes for small cells powered by renewable energy sources. Third, leveraging the evolving mobile core with in-network caching, we will develop smart routing algorithms that can reduce energy consumption by shifting traffic while ensuring user quality-of-experience (QoE). This research is expected to benefit Canadian industry by providing guidelines and references for wireless service providers to expand their service capacity while saving capital/operating expenditures. There will also be significant benefits to Canadian society through energy conservation for environment protection. Highly-qualified personnel will be trained in this program and will contribute to the progress of green wireless networks.

过去十年见证了巨大的移动流量、无处不在的智能设备和各种新应用的爆炸性增长。虽然这一增长带来了全球移动行业收入的增加，但人们越来越担心环境影响和高昂的资本/运营支出。在经济和生态两个角度的迫切需求的推动下，节能和绿色成为5G无线网络的主导主题之一。虽然这样的需求已经引起了学术界和工业界的相当大的关注和努力，但不断发展的网络体系结构需要不断地使用绿色网络算法来增强，以充分挖掘潜力。与此同时，新的用户驱动的应用程序不断涌现，需要高效的解决方案来保持可持续增长。 这项研究计划将通过探索能源感知技术，利用不断发展的网络架构、更智能的移动设备和大量新兴应用的多样化特征，为向下一代绿色无线网络的演进做出贡献。特别是，我们将重点推进三个推进。首先，利用智能设备的智能，我们将开发新的算法，用于协作集群分组、任务分配和用户参与激励。还将通过平衡吞吐量性能和能量消耗来研究具有用户协作的节能多路径传输协议。第二，利用多层无线接入网络，为不同类型的基站开发流量感知睡眠方案，为可再生能源供电的小小区开发服务差异化调度方案。第三，利用不断发展的具有网络内缓存的移动核心，我们将开发智能路由算法，该算法可以通过转移流量来降低能耗，同时确保用户体验质量(QOE)。 这项研究预计将为无线服务提供商在节省资本/运营支出的同时扩大服务能力提供指导和参考，从而使加拿大工业受益。通过节约能源来保护环境，也将给加拿大社会带来重大好处。高素质的人员将接受这一计划的培训，并将为绿色无线网络的进步做出贡献。
