IEEE 802.11 is an evolving standard used throughout the Internet. Recent advances in wireless communication have been incorporated into IEEE 802.11-based standards. IEEE 802.11n and 802.11ac, for example, offer new mechanisms that enable a multifold increase in transmission speeds relative to 802.11a/b/g. Newly available features make configuring a network, and the devices which use it, a critical challenge. The performance of even the most sophisticated networks suffer debilitating degradation if the network is improperly configured. This project is focused on the following questions: 1) What gains can be achieved by closed-loop 802.11n/ac rate adaptation solutions? 2) How can IEEE 802.11 features better be utilized in a rate adaptation solution? 3) How responsive and adaptive should a real-time channel monitoring solution be? and 4) How can the cost of expensive Channel State Information be minimized? By designing new network configuration mechanisms and observing the performance of these mechanisms in a wide variety of real-world deployment scenarios, wireless network performance and robustness are being improved.As the scale of wireless network deployments grows, the need for effective network configuration mechanisms is critical. The work in this project is developing highly flexible protocol enhancements that are adding significant new performance and robustness capabilities to wireless networks running the newest IEEE 802.11 standards. Through scientific publications, conference presentations, and industrial collaborations, the outcomes of this project will be made available to wireless equipment vendors, thereby achieving tangible improvements in Internet performance.

IEEE 802.11是一个不断发展的标准，在整个互联网中使用。 无线通信的最新进展已经被并入基于IEEE 802.11的标准中。 例如，IEEE 802.11 n和802.11 ac提供了新的机制，使传输速度相对于802.11 a/B/g成倍增加。 新的可用功能使配置网络和使用它的设备成为一个关键的挑战。 如果网络配置不当，即使是最复杂的网络的性能也会下降。本项目重点研究以下问题：1）闭环802.11n/ac速率自适应解决方案可以实现哪些增益？2)如何在速率自适应解决方案中更好地利用IEEE 802.11特性？3)实时通道监控解决方案的响应性和适应性如何？以及4）如何使昂贵的信道状态信息的成本最小化？通过设计新的网络配置机制并观察这些机制在各种实际部署场景中的性能，无线网络的性能和鲁棒性正在得到改善。随着无线网络部署规模的增长，对有效的网络配置机制的需求至关重要。 该项目的工作是开发高度灵活的协议增强功能，为运行最新IEEE 802.11标准的无线网络增加重要的新性能和鲁棒性。 通过科学出版物、会议演示和行业合作，该项目的成果将提供给无线设备供应商，从而实现互联网性能的切实改善。
