Energy Efficient Architectures and Protocols for Beyond-4G Mobile Cellular Networks

用户对新的和新兴的无线服务不断增长的被压抑的需求正在推动对未来一代宽带(大容量)无线网络的需求，例如超越第四代(Beyond-4G)移动蜂窝网络。然而，这种宽带无线网络的能源消耗正成为一个严重的问题，这不仅是因为网络运营商的运营支出增加(由于当今能源成本不断上升)，而且还因为二氧化碳(CO2)排放产生的相关环境影响，因为用于为无线网络基础设施供电的电力是由化石燃料产生的。提出的研究的主要目标是使下一代宽带移动蜂窝网络节能、环保和经济可持续。 我建议设计、分析和评估原始的和创新的网络体系结构和协议，以实现上述目标。具体地说，我将研究异质基站网络和协作中继网络的体系结构。我的研究将提出并发现用于数据传输、多址接入和资源管理的节能协议和算法，并利用无线应用和服务的特点来实现节能。我将研究在不同层提出的协议之间的相互作用，以进一步实现更高的能源效率。将开发新的理论技术来进行绩效评估，以获得有价值的见解。 我的研究将为社会需求之一提供解决方案：通过减少下一代宽带无线网络带来的碳足迹来实现绿色环境。此外，我建议的研究计划将为研究生提供节能宽带无线网络的技术培训，他们迫切需要的技能对加拿大无线行业的持续增长至关重要。

The increasing pent-up demand by users for new and emerging wireless services is driving the need for future generation broadband (high capacity) wireless networks, such as the Beyond-Fourth Generation (Beyond-4G) mobile cellular networks. However, the energy consumption of such broadband wireless networks is becoming a serious concern, not only because of increased operational expenditure to the network operators (due to the escalating cost of energy nowadays) but also in terms of the associated environmental impacts arising from carbon dioxide (CO2) emissions, as the electricity used to power the wireless network infrastructure is generated by fossil fuels. The main goal of the proposed research is to make the future generation broadband mobile cellular networks energy efficient, to be environmentally friendly, and economically sustainable. I propose to design, analyze and evaluate original and innovative network architectures and protocols to achieve the above goal. Specifically, I shall investigate both the heterogeneous base station network and cooperative relay network architectures. My research will propose and discover energy efficient protocols and algorithms for data transmission, multiple access and resource management, and also exploit the characteristics of wireless applications and services to achieve energy efficiency. I shall study the interactions amongst the protocols proposed at different layers to further achieve increased energy efficiency. Novel theoretical techniques will be developed for performance evaluation, to gain valuable insights. My research will offer a solution to one of society's needs: achieving a green environment, through a reduction in the carbon footprint induced by future generation broadband wireless networks. Furthermore, my proposed research program will provide technical training in energy efficient broadband wireless networking to graduate students whose highly desired skills are vital for continued growth of the Canadian wireless industry.
