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

移动系统受益于能够实现安全、可靠和可扩展移动性的基础设施。在车辆移动系统中，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，引入了创新的光无线通信（OWC）方法。OWC方法由于其潜在的高数据速率和范围、安全优势、低成本、延迟和功耗而显示出前景。然而，大多数现有的基于owc的车载移动系统技术只能在单一方向上进行通信。这减少了通信视野，因此在移动系统中共享位置和路线规划信息的能力。该项目的新颖之处在于探索新的基于owc的技术，以提高在高数据速率下多方向通信的能力，并提供精确定位移动节点的技术，以支持可扩展和协作的移动系统。该项目更广泛的意义和重要性在于提高交通控制能力，以及机器人、无人机和移动车辆系统的协作能力。该项目的目标是通过基于owc的技术支持可靠和可扩展的移动系统协作通信和定位，包括三个研究组成部分：(1)全息光学标签设计，实现移动节点之间的智能协作，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协同实现分布式移动定位，支持实时、动态、可扩展的分布式移动定位系统；(3)为多对多组网设计轻量级中间件，提供全方向而非单向通信，形成动态多对多移动网络。该奖项反映了美国国家科学基金会的法定使命，并通过使用基金会的知识价值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.
