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，我们正在经历无线网络流量的爆炸，这是由迅速增长的移动设备和带宽应用应用程序驱动的。行业研究预测，到2020年，总的带宽需求增加了1000倍。尽管有数十年的研究提高了WiFi和蜂窝网络的光谱效率，但现有技术只能提供短期解决方案。 IEEE 802.11AD标准支持的无牌60 GHz频段中的毫米波（MMWAVE）技术最近出现了传统WiFi的替代方案，有望每秒吞吐量。然而，警告是由于波长较小而导致了高度衰减和易受阻塞MMWave信号的脆弱性。例如，发射器和接收器之间的视线（LOS）中人体的存在可能导致完整的链接中断。该项目旨在实施一项综合的研究和教育计划，以对MMWave频带中的多观念型WLAN具有雄心勃勃的愿景，该频段将在家庭和企业环境中始终提供连通性，但是与当前WiFi网络相比，在2.4/5 GHz频段中，当前WiFi网络的吞吐量要高2.4/5 GHz频段。 MMWave通道及其对高层性能的影响，并逐渐向上移动网络堆栈的层。具体而言，该项目包括以下任务：（i）MMWAVE无线通道的测量和建模，协议堆栈的不同层之间的相互作用以及MMWave网络交互的功耗，（II）模型驱动的MAC协议设计（速率和光束适应速率和光束适应，适应性框架，适应性框架聚集，损失诊断），构建性能和启动连接，（III II II II）（III）（III（II II）（II II）（II II）（II II）（II II）（II II）（II II）（II II）（MMMM MM MM MM MM MM MM MM MM MM MM MM MM MM MM MM MM MM MM MM MM MM MM MM MM。人体阻塞的情况），扩展网络覆盖范围，增加无线容量，以及在线链接测量框架以及一组最佳继电器选择的指标。拟议的体系结构将在60 GHz测试床上进行原型和评估，由现成和专有硬件平台的组合组成，该平台将作为该项目的一部分开发。此外，该项目将开发一个新的多层次逼真的60 GHz模拟器，以进行大规模评估，并将其提供给无线网络社区。
