项目摘要

Future Internet-of-Things (IoT) applications will increasingly rely on the exchange of delay sensitive information. Application domains such as autonomous vehicles, industrial control systems, virtual reality, and sensor networks, heavily rely upon the distribution of time-critical information. Age of Information (AoI) is a recently proposed performance metric that measures the freshness of the information from the perspective of the application. AoI measures the time that elapsed from the moment that the most recently received data was generated to the present time. This project develops an AoI framework for characterizing latency in wireless networks, and mechanisms for minimizing latency; thus enabling a wide range of societal benefits including the control of critical infrastructure, mobile health care, and automated manufacturing. The goal of this project is to extend the Age-of-Information framework to the wireless network setting. In particular, this project advances the theory of AoI from the simple and abstract queueing models to realistic wireless network models, taking into account the effects of wireless interference, transmission scheduling, and multi-hop routing. The project will consider single-hop networks, such as LTE or WiFi; multi-hop networks such as sensor networks; and mobile ad-hoc networks. The goal is to understand the impact of network topology, node mobility, interference and channel reliability on AoI, and to develop network control mechanisms that minimize AoI under different wireless network settings. The project will progressively extend the AoI framework to the wireless setting: Starting with simple single-hop networks and extending to mobile multi-hop networks. The research agenda includes the following tasks: 1)Single-Hop Wireless Networks: Develop methods to analyze AoI in single-hop wireless networks, and devise transmission scheduling schemes for minimizing AoI; 2) Multi-Hop Networks: develop routing and scheduling schemes for minimizing AoI in multi-hop wireless networks; and 3)Mobile Wireless Networks: develop fundamental limits on AoI in mobile networks, and develop packet relaying schemes for minimizing AoI.

未来的互联网应用程序（IoT）应用程序将越来越多地依赖延迟敏感信息的交换。诸如自动驾驶汽车，工业控制系统，虚拟现实和传感器网络之类的应用领域在很大程度上依赖于时间关键信息的分布。信息时代（AOI）是最近提出的性能指标，它从应用程序的角度来衡量信息的新鲜度。 AOI衡量从最新收到的数据到当前时间的那一刻开始的时间。该项目开发了一个AOI框架，用于表征无线网络中的延迟，以及最小化延迟的机制；因此，可实现广泛的社会利益，包括控制关键基础设施，移动医疗保健和自动制造业。该项目的目的是将信息年龄框架扩展到无线网络设置。特别是，考虑到无线干扰，传输调度和多跳路由的影响，该项目将AOI的理论从简单和抽象的排队模型到现实的无线网络模型发展。该项目将考虑单跳网络，例如LTE或WiFi；多跳网络，例如传感器网络；和移动临时网络。目的是了解网络拓扑，节点移动性，干扰和渠道可靠性对AOI的影响，并开发网络控制机制，以最大程度地减少不同无线网络设置下的AOI。该项目将逐步将AOI框架扩展到无线设置：从简单的单跳网络开始，然后扩展到移动多跳网络。研究议程包括以下任务：1）单跳无线网络：开发分析单跳无线网络中AOI的方法，并设计传输计划方案以最大程度地减少AOI； 2）多跳网络：开发路由和调度方案，以最大程度地减少多跳无线网络中的AOI； 3）移动无线网络：在移动网络中对AOI的基本限制开发，并开发数据包中继方案以最大程度地减少AOI。
