CRII: NeTS: Real-life modeling for EFficient RESource management in Heterogeneous multi-user systems - REFRESH

新兴的5G和网络物理社会系统的经济和社会潜力远远大于迄今所实现的，世界各国正在大力投资发展相应的科学技术。尽管在研究这种互联系统的各种架构的发展方面取得了重大成就，但阻碍进一步进展的一个障碍是缺乏适当的科学技术来概念化和设计用户行为、交互和决策之间的深度相互依赖关系。这个名为REFRESH的项目推动了一个新的研究议程，其中提出的资源管理框架和现实生活建模方法超越了传统的设置。提出的方法允许创建以用户为中心的框架，为(a)最终用户带来显著的好处，在降低功耗、降低价格和减少通信和计算开销方面；(b)对于网络或服务提供商而言，在节约能源和增加满意客户数量方面。拟议的研究不仅将影响相应的科学方向，而且将刺激新兴规模经济的变化，为社会增长和范式转变创造基础。将项目的广泛影响最大化的具体计划包括教育活动、外联行动、少数民族学生招募、多样性和数据传播行动。在REFRESH中考虑了一种新的无线网络资源分配方法，基于以下思想：(a)不是最大化服务质量（QoS），而是认为更好的能源效率是通过只瞄准令人满意的QoS水平来实现的。这可以用博弈论的解决方案概念来处理，即满足均衡；(b)迄今为止所使用的理论没有设法适当地解决这样一个事实，即个人在现实生活中并不表现为中立的预期效用最大化者，而是在不确定性下倾向于表现出寻求风险或厌恶损失的行为。为了解决这个问题，前景理论和公地悲剧理论被运用。通过整合学习方法来减少通信和计算环境的动态性和信息缺乏的影响，补充了引入的新资源分配范式的现实性。预期的结果有可能为坚实的理论和实际的资源管理框架奠定基础。该项目由计算机和网络系统（CNS）计划和促进竞争研究的既定计划（EPSCoR）共同资助。该奖项反映了美国国家科学基金会的法定使命，并通过使用基金会的知识价值和更广泛的影响审查标准进行评估，被认为值得支持。

The economic and societal potential of emerging 5G and cyber-physical social systems is vastly greater than what has been realized so far, and major investments are being made worldwide to develop the corresponding science and technology. Though significant achievements have been obtained in the development of various architectures to study such interconnected systems, one barrier to further progress is the lack of appropriate science and technology to conceptualize and design for the deep inter-dependencies among users behaviors, interactions, and decisions. This project, called REFRESH, promotes a novel research agenda, where the proposed resource management framework and the real-life modeling approach go beyond the classical settings. The proposed approach allows for the creation of a user-centric framework that brings significant benefits for (a) the end-user, in terms of reduced power consumption, lower prices and reduced communication and computation overhead; and (b) for the network or service provider, in terms of energy savings and increased number of satisfied customers. The proposed research will influence not only the corresponding scientific directions but will stimulate changes in the emerging economies of scale, creating the basis for societal growth and paradigm shifts. Concrete plans to maximize the broader impacts of the project include educational activities, outreach actions, minority student recruitment, diversity, and data dissemination actions.In REFRESH a novel approach to resource allocation in wireless networks is considered, based on the following ideas: (a) Instead of maximizing the Quality of Service (QoS), it is argued that better energy-efficiency is achieved by targeting satisfactory QoS levels only. This is treated by a game-theoretical solution concept referred to as satisfaction equilibrium; (b) The theory used so far has not managed to properly address the fact that individuals in real-life do not behave as neutral expected utility maximizers, but they tend to exhibit risk-seeking or loss-aversion behavior under uncertainty. To deal with this, Prospect Theory and the theory of the Tragedy of the Commons are exploited. The realism of the introduced novel resource allocation paradigm is complemented by integrating learning approaches to reduce the impact of communication and computing environment dynamicity and lack of information. Expected findings have the potential to lay the foundations of a solid theoretical and pragmatic resource management framework.This project is jointly funded by the Computer and Network Systems (CNS) program and the Established Program to Stimulate Competitive Research (EPSCoR).This award reflects NSF's statutory mission and has been deemed worthy of support through evaluation using the Foundation's intellectual merit and broader impacts review criteria.
