NeTS-WN: Wireless Network Health: Real-time Diagnosis, Adaptation, and Management

最近的互联网扩张，至少在地理覆盖方面，很大程度上是利用无线技术实现的。这项研究拨款的目标是通过实时网络诊断和动态适应，部署具有服务能力和响应性的无线网络。只有通过集成实时测量和分析(由网络设备进行本地化的自主适应，并通过可视化和交互分析进行管理)，无线网络才能实现长期的实用性和稳定性，同时还可以为日益复杂的服务提供支持。该项目的研究分为五个领域：动态监控，包括提高监控数据的准确性以及执行有针对性的高保真监控的实时能力；网络健康诊断，试图确定各种指标的实时运行状态；动态配置，使用状态信息调整网络运行和协议参数，以提高性能；交互式可视化，试图通过交互式和可扩展的显示技术帮助了解网络；以及管理和规划，从更长远的角度看待无线网络运营，并侧重于额外资源放置等功能。这些项目通过无线网络的新设计提供智力优势，努力开发一套清晰的设计解决方案，调查每套解决方案中可能的替代方案，并评估建议的解决方案。这项研究将对研究、产业、社会和教育产生广泛的影响。它将为研究提供新的方向，影响无线网络的设计和部署，并提高无线网络部署的健壮性。

Recent Internet expansion, at least in terms of geographical coverage, has largely occurred using wireless technology. The goal of this research grant is to enable the deployment of service-capable and responsive wireless-based networks through real-time network diagnosis and dynamic adaptation. Only through an integration of real-time measurement and analysis (localized, autonomous adaptation by network devices, and management though visualization and interactive analysis) can wireless networks achieve long-term utility and stability while also providing support for increasingly complex services. The research in this project is divided into five areas: dynamic monitoring, which includes work to improve the accuracy of monitored data as well as the real-time capability to perform targeted high-fidelity monitoring; network health diagnosis, which attempts to determine the real-time operational status of a variety of metrics; dynamic provisioning, which uses status information to adjust network operation and protocol parameters in order to improve performance; interactive visualization, which attempts to aid network understanding through interactive and scalable display techniques; and finally, management and planning, which takes a longer-term view of wireless network operations and focuses on capabilities like additional resource placement. These projects provide intellectual merit through new designs for wireless networks, work to develop a clear set of design solutions, investigation of possible alternatives within each set, and evaluation of proposed solutions. The research will have a broad impact on research, industry, society, and education. It will offer new directions in research, impact wireless network design and deployment, and improve the robustness of wireless network deployments.
