A planning and performance perspective for next generation green communication networks

由于互联网无线应用的日益普及、物联网的曙光以及管理大量数据的需求，电信网络正在发生根本性的变化。随着这些发展，人们越来越意识到互联网和通信技术（ICT）对生态能源的影响，并研究了许多硬件、算法和软件建议。在这个项目中，我们处理这些网络的规划、性能和鲁棒性方面，进一步探索一个关键思想：在建模中预先整合绿色能源和节能选项的通信网络，最终比那些在用传统方法规划后实施绿色选项的通信网络具有更高的能源和性能效率。我们将首先调查当前无线网络的规划问题，如果它们使用绿色能源。接下来，我们将从网络规划、性能和可靠性的角度探讨不同架构、虚拟化和云方案的影响。特别是，我们建议通过详细的规划模型来研究无线供电通信在网络层面的可行性，并深入研究不断发展的C-RAN提案的能源成本，网络性能和网络鲁棒性的权衡。该项目的长期愿景是能够设计未来的网络，以大量的绿色能源运行，日益减少对传统能源形式的依赖，同时保证新型应用所需的端到端网络性能。在短期和中期，我们希望在即将到来的无线网络中研究不同的规划和操作权衡，包括能源、虚拟化、性能和可靠性。

We are witnessing radical changes in telecommunication networks that are driven by the increasing popularity of Internet wireless applications, the dawn of the Internet of things and the need to manage large amounts of data. Alongside these developments, there has been an increasing awareness on the eco-energy impact of Internet and Communications Technology (ICT) and many hardware, algorithmic and software proposals have been studied. In this project we deal with the planning, performance and robustness aspects of those networks, further exploring a key idea: communication networks that are planned integrating beforehand green energy and energy-efficient options in the modeling end up being much more energy and performance efficient than those on which green options are implemented after being planned with traditional methods. We will start by investigating planning issues of current wireless networks if they were operating with green sources. Next, we explore the impact of different architectural, virtualization and cloud proposals under a network planning, performance and reliability perspective. In particular, we propose to study the feasibility of Wireless powered communications at the network level, through detailed planning models and get in-depth into the trade-offs of energy-costs, network performance and network robustness of the evolving C-RAN proposals.The long-term vision of the project is being able to design forthcoming networks to operate with a large amount of green energy, increasingly reducing the dependence on traditional forms of energy, while guaranteeing the end-to-end network performance required by the new types of applications. In the shorter and medium term, we want to investigate different planning and operating trade-offs concerning energy, virtualization, performance and reliability in forthcoming wireless networks.
