Although wireless networks have advanced significantly over the last few years, newly emerging applications such as augmented/virtual reality and ultra high-definition video streaming and the continuous growth of mobile and wearable devices are leading to higher than ever mobile traffic demand. It is becoming apparent that today's wireless networks (such as 2.4/5 GHz Wi-Fi) are struggling to satisfy the demand and there is a need for designing the next generation of wireless networks that can provide significantly higher data rates in a reliable manner. Wireless communication using the 60 GHz unlicensed millimeter-wave spectrum has shown the potential to bridge this gap by providing multi-gigabit per second data rates. Designing enterprise-grade 60 GHz millimeter-wave wireless networks is challenging due to directionality and severe performance degradations observed in presence of human blockages. The main objective of this project is to design proactive blockage mitigation techniques based on network coordination that can enable high data rate wireless links while ensuring reliability in presence of mobility and blockages. The project will have immediate impact on research and development of high-speed millimeter-wave mobile wireless networks. It will result in hands-on wireless networking research experience for undergraduate and graduate students. The aim of this project is to investigate a novel class of proactive blockage mitigation techniques based on coordination between the access points of 60 GHz WLANs. The proposed research exploits joint transmissions from multiple access points to mobile devices. With intelligent selection of access points and antenna sectors, such joint transmissions can provide adequate spatial diversity and separation of angle-of-arrival, resulting in robust communication in presence of self-body blockages. The project will use measurements, modeling and optimization to design, analyze and evaluate joint transmissions. First, multi-state performance degradation models for link blockages will be developed using measurements. The models will be used to design novel reliability metrics for assessing the robustness provided by joint transmissions. Second, based on the measurement-driven models, a joint access point selection and link scheduling problem will be studied with the aim of maximizing network throughput taking into account reliability-spatial reuse trade-offs. Third, the impact of joint transmissions on link layer delay will be studied using measurements on 360-degree live video streaming over 60 GHz links, and delay sensitive scheduling strategies will be investigated. The proposed research will be evaluated using 60 GHz off-the-shelf devices and a software-radio platform with phased antenna arrays.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.

尽管无线网络在过去几年中取得了显著的进步，但是诸如增强/虚拟现实和超高清视频流之类的新兴应用以及移动的和可穿戴设备的持续增长正在导致比以往更高的移动的流量需求。越来越明显的是，当今的无线网络（诸如2.4/5GHz Wi-Fi）正在努力满足需求，并且需要设计能够以可靠的方式提供显著更高的数据速率的下一代无线网络。使用60 GHz未经许可的毫米波频谱的无线通信已经显示出通过提供每秒数千兆位的数据速率来弥合这一差距的潜力。设计企业级60 GHz毫米波无线网络具有挑战性，因为存在人为阻塞时会出现方向性和严重的性能下降。该项目的主要目标是设计基于网络协调的主动阻塞缓解技术，该技术可以实现高数据速率无线链路，同时确保存在移动性和阻塞时的可靠性。该项目将对高速毫米波移动的无线网络的研究和开发产生直接影响。它将导致动手无线网络研究经验的本科生和研究生。本项目的目的是研究一类新型的主动阻塞缓解技术的基础上协调接入点之间的60 GHz无线局域网。所提出的研究利用从多个接入点到移动的设备的联合传输。通过接入点和天线扇区的智能选择，这样的联合传输可以提供足够的空间分集和到达角的分离，从而在存在自体阻塞的情况下实现稳健的通信。该项目将使用测量，建模和优化来设计，分析和评估联合传动。首先，多状态性能退化模型的链路阻塞将开发使用测量。该模型将用于设计新的可靠性指标，用于评估联合传输提供的鲁棒性。其次，基于测量驱动的模型，联合接入点选择和链路调度问题进行了研究，其目的是最大化网络吞吐量，同时考虑到可靠性空间复用的权衡。第三，联合传输对链路层延迟的影响将使用测量在60 GHz链路上的360度实时视频流进行研究，并将研究延迟敏感的调度策略。拟议的研究将使用60 GHz现成设备和带有相控天线阵列的软件无线电平台进行评估。该奖项反映了NSF的法定使命，并通过使用基金会的知识价值和更广泛的评估被认为值得支持影响审查标准。
