We are experiencing today an explosion in wireless network traffic driven by the rapidly growing number of mobile devices and bandwidth-hungry applications. Industry research predicts a 1000-fold increase in aggregate bandwidth demands by 2020. In spite of decades of research on improving spectrum efficiency in WiFi and cellular networks, existing techniques can only offer short-term solutions. Millimeter-wave (mmWave) technology in the unlicensed 60 GHz band, supported by the IEEE 802.11ad standard, has recently emerged as an alternative to legacy WiFi, promising multi-Gigabit per second throughput. The caveat, however, is the high attenuation and vulnerability to blockage of mmWave signals, due to the small wavelength. For example, the presence of a human body in the Line-of-Sight (LOS) between the transmitter and the receiver can result in a complete link outage. This project aims to implement an integrated research and education plan towards an ambitious vision of general purpose multi-Gigabit WLANs in the mmWave frequency bands that will offer always-on connectivity in home and enterprise environments but an order of magnitude higher throughput than current WiFi networks in 2.4/5 GHz bands.To realize this vision, the project will develop a mmWave multi-layer WLAN architecture in a systematic, bottom-up fashion, starting with an understanding of the mmWave channel and its impact on higher layer performance and gradually moving up the layers of the network stack. Specifically, the project includes the following tasks: (i) measurement and modeling of the mmWave wireless channel, the interactions among different layers of the protocol stack, and the power consumption of mmWave network interfaces, (ii) model-driven MAC protocol design (rate and beam adaptation, adaptive frame aggregation, loss diagnosis) targeting both performance and power savings, (iii) a mmWave relay architecture for improving connectivity (in the case of human blockage), extending network coverage, and increasing wireless capacity, along with an online link measurement framework, and a set of metrics for optimal relay selection. The proposed architecture will be prototyped and evaluated on a 60 GHz testbed, consisting of a combination of off-the-shelf and proprietary hardware platforms, which will be developed as part of this project. Additionally, the project will develop a new multi-level realistic 60 GHz simulator for large scale evaluation and will make it available to the wireless networking community.

今天，由于移动设备和带宽需求大的应用程序数量的快速增长，我们正在经历无线网络流量的爆炸式增长。行业研究预测，到 2020 年，总带宽需求将增加 1000 倍。尽管对提高 WiFi 和蜂窝网络频谱效率进行了数十年的研究，但现有技术只能提供短期解决方案。由 IEEE 802.11ad 标准支持的非授权 60 GHz 频段的毫米波 (mmWave) 技术最近已成为传统 WiFi 的替代方案，有望实现每秒数千兆位的吞吐量。然而，需要注意的是，由于波长较小，毫米波信号的衰减较高且容易被阻塞。例如，发射器和接收器之间的视线 (LOS) 中存在人体可能会导致链路完全中断。该项目旨在实施一项综合研究和教育计划，以实现毫米波频段通用多千兆位 WLAN 的雄心勃勃的愿景，该愿景将在家庭和企业环境中提供始终在线的连接，但吞吐量比当前 WiFi 网络高一个数量级为了实现这一愿景，该项目将以系统的、自下而上的方式开发毫米波多层WLAN架构，首先了解毫米波信道及其对高层性能的影响，然后逐步转向向上层网络堆栈的。具体来说，该项目包括以下任务：（i）毫米波无线信道的测量和建模、协议栈不同层之间的交互以及毫米波网络接口的功耗，（ii）模型驱动的MAC协议设计（ (iii) 毫米波中继架构，用于改善连接性（在人为堵塞的情况下）、扩展网络覆盖范围和增加无线容量，以及在线链接测量框架和一组指标以获得最佳的继电器选择。拟议的架构将在 60 GHz 测试台上进行原型设计和评估，该测试台由现成的和专有的硬件平台组合而成，这些平台将作为该项目的一部分进行开发。此外，该项目还将开发一种新的多级真实 60 GHz 模拟器，用于大规模评估，并将其提供给无线网络社区。
