EAGER: Systems of Holographic Optical Tags for Scalable and Collaborative Mobile Infrastructures

移动系统受益于支持安全、可靠和可扩展移动性的基础设施。在车载移动系统中，许多研究都考虑了车辆协作共享位置和路线规划信息的通信和系统技术。这些系统对延迟和可靠性有严格的限制。移动系统的通信网络通常依赖于基于无线电频率的方法。射频网络在高能耗、传输速率和安全攻击方面存在局限性。为了克服这些限制，创新的光无线通信(OWC)方法应运而生。OWC方法因其潜在的高数据速率和范围、安全优势以及低成本、低延迟和低功耗而显示出良好的前景。然而，现有的大多数基于OWC的车载移动系统技术只能实现单向通信。这减小了通信视野，从而降低了在移动系统中共享位置和路线规划信息的能力。该项目的创新之处在于探索基于OWC的新技术，以提高在高数据速率下多方向通信的能力，并提供准确定位移动节点的技术，以支持可扩展和协作的移动系统。该项目的更广泛的意义和重要性是提高交通控制能力，以及机器人、无人机和移动车辆系统的协作。本项目的目标是通过基于OWC的技术为移动系统提供可靠和可扩展的协作通信和定位支持，包括三个研究组成部分：(1)全息光学标签设计，使移动节点之间能够进行智能协作，以提高性能，如更准确的定位、更好的解码、全方向通信和更高的吞吐量；(2)通过低成本全息光学标签的协作，支持实时、动态和可扩展的分布式移动定位系统；以及(3)多对多网络的轻量级中间件设计，以提供全方向而不是单向通信，并形成动态的多对多移动网络。该奖项反映了NSF的法定使命，并通过使用基金会的智力优势和更广泛的影响审查标准进行评估，被认为值得支持。

Mobile systems benefit from infrastructures that enable safe, reliable, and scalable mobility. Within vehicular mobile systems, much research has considered communication and system technologies in which vehicles collaborate to share location and route planning information. These systems have strict constraints for delay and reliability. The communication networks of the mobile systems typically rely upon radio frequency-based approaches. Radio frequency networks have limitations regarding high energy consumption, transmission rates, and security attacks. To overcome these limitations, innovative optical wireless communication (OWC) approaches have been introduced. OWC approaches show promise due to their potential high data rates and range, security advantages, and low cost, delay, and power consumption. However, most existing OWC-based techniques for vehicular mobile system enable communication only in a single direction. This reduces the communication field of view and therefore the ability to share location and route planning information in a mobile system. The project’s novelties are to explore new OWC-based techniques to improve capabilities for communication in multiple directions at high data rates and provide techniques for accurate positioning of mobile nodes to support scalable and collaborative mobile systems. The project's broader significance and importance are improving the capabilities of traffic control, and the collaboration of robots, drones, and mobile vehicular systems. The objective of this project is to support reliable and scalable collaborative communication and localization for mobile systems via OWC-based technologies with three research components: (1) holographic optical tag design to enable smart collaboration among mobile nodes for improved performance, such as more accurate positioning, better decoding, full directional communication and higher throughput; (2) distributed mobile localization via collaboration of low-cost holographic optical tags to support real-time, dynamic, and scalable distributed systems for mobile localization; and (3) lightweight middleware design for multi-to-multi networking to provide full direction instead of monodirectional communication and to form dynamic multi-to-multi mobile networks.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.
