US-Ireland Partnership: WiPhyLoc8: Dynamic WiFi Positioning using Physical Layer Parameters for Location-based Services and Security

目标：该计划的目标是创新研究新的变革性算法，使用低成本WiFi技术提供高精度定位服务。物理层RF信号的特性将被用来创建变革性的定位算法，这对下一代室内导航、网络安全、紧急疏散和商业服务至关重要。该计划连接研究人员从莱斯大学（RU），大学学院都柏林（UCD）和女王？的贝尔法斯特大学（QUB），在定位算法（UCD）、基带/FPGA处理架构（QUB/RU）、WiFi物理层网络（RU/QUB）和定位应用（UCD/QUB）方面拥有专业知识; UCD和QUB的工作由其国家资助机构资助。智力优势：智力优势是创建了Spotlight和Location-Sync算法，以在真实室内环境中实现亚米级精度。Spotlight将利用接入点的多个天线和波束控制来实现发射方向-接收信号强度组合签名，从而减少多路径和遮挡。位置同步使用飞行时间方法来测量WiFi节点之间的距离;它通过联合时钟同步和位置估计以及随时间和多个节点之间的时钟和距离参数的融合来提高精度。更广泛的影响：更广泛的影响是显著改善基于位置的服务，通过更有效的室内行人导航使更广泛的社区受益。除了研究出版物，为WiPhyLoc 8平台（Rice University WARP with Xilinx 10 G NetFPGA）分发的模块将提供网络安全和地理围栏应用中的算法性能测量。WiPhyLoc 8项目计划开发开放获取的教育材料和学期课程。

Objective:The objective of this program is innovative research in new transformative algorithms for high-precision localization services using low-cost WiFi technology. Features of the Physical Layer RF signal will be exploited to create transformative localization algorithms which are vital for next generation indoor navigation, network security, emergency evacuation and commercial services. The program connects researchers from Rice University (RU), University College Dublin (UCD) and Queen?s University Belfast (QUB) with expertise in localization algorithms (UCD), baseband/FPGA processing architectures (QUB/RU), WiFi Physical Layer networking (RU/QUB) and localization applications (UCD/QUB); the UCD and QUB work is funded by their national funding agencies.Intellectual Merit: The intellectual merit is the creation of the Spotlight and Location-Sync algorithms to achieve sub-meter accuracy in real-world indoor environments. Spotlight will utilize multiple antennae at the Access Point and beamsteering for a combined Direction of Emission - Receive Signal Strength signature, thereby reducing multi-path and occlusion. Location-Sync uses a Time of Flight approach to measure the range between WiFi nodes; it enhances precision through joint clock synchronization and location estimation and fusion of clock and range parameters over time and between multiple nodes. Broader Impact: The broader impacts are significant improvements to Location Based Services benefitting the wider community through more effective indoor pedestrian navigation. In addition to research publications, the modules distributed for the WiPhyLoc8 platform (Rice University WARP with Xilinx 10G NetFPGA) will provide algorithm performance measurements in network security and geofencing applications. The WiPhyLoc8 project plans to develop open-access educational materials and semester length courses.
