Mobile ad-hoc communication is starting to find real-world applications beyond its military origins, in areas such as vehicular communications and delay tolerant networking. As the RF spectrum is getting saturated by recent advances in wireless communications, enabling optical spectrum in wireless communications is the needed revolution for ultra-high-speed mobile ad-hoc networks (MANETs) of the future. This project explores the potential for free-space-optics (FSO) in the context of very-high-speed mobile ad-hoc and opportunistic networking. Intellectual Merit: This project introduces basic building blocks for MANETs using FSO and prototypes multi-hop high-capacity FSO building blocks and protocols operating under high mobility. 3-d spherical structures covered with inexpensive FSO transceivers (e.g., VCSEL and photo-detector pair) solve issues relevant to mobility and line-of-sight (LOS) management via availability of several transceivers per node. Such structures facilitate electronic LOS tracking (i.e., ?electronic steering?) methods instead of traditional mechanical steering techniques. The project also investigates reliability protocols as management of logical datastreams through multi-interface FSO structures pose a major challenge. By abstracting FSO directionality and LOS characteristics, the project explores issues relating to routing and localization, and develops layer 3 protocols and FSO-MANET demonstration in a lab setting.Broader Impact: Results of this research can revolutionize the MANET technologies by enabling optical spectrum. FSO has been used at high-altitude communications, and this project enables FSO communications at lower-altitudes and in ad-hoc settings. This research will provide a new application for solid-state lighting technology due to potential integration of illumination and communication functions. Other impact areas include: sensor networks, peer-to-peer networks leveraging directional overlay protocols, and military wireless applications such as UAV/aircraft airborne networks and inter-ship communications.

移动临时通信开始在车辆通信和延迟耐受网络等领域中找到超出其军事起源的现实应用程序。随着无线通信最近进步的RF频谱使无线通信中的光谱范围变得越来越饱和，这是未来超高速移动临时网络（MANETS）所需的革命。该项目探讨了在非常高速的移动临时和机会主义网络的背景下自由空间启示（FSO）的潜力。知识分子的优点：该项目使用FSO和原型多跳跃高容量的FSO构建块和协议在高移动性下运行的协议引入了基本的构建块。 3-D球形结构覆盖了廉价的FSO收发器（例如VCSEL和Photo-detector对）通过每个节点的多个收发器可用性来解决与移动性和视线（LOS）管理相关的问题。这样的结构促进了电子LOS跟踪（即？电子转向？）方法，而不是传统的机械转向技术。该项目还通过多间接FSO结构提出了一个重大挑战，研究可靠性协议作为逻辑数据流的管理。通过抽象FSO方向性和LOS特征，该项目探讨了与路由和本地化有关的问题，并在实验室环境中开发了3层协议和FSO-Manet演示。BRODER的影响：这项研究的结果可以通过启用光学谱系来彻底改变MANET技术。 FSO已在高空通信中使用，该项目可以在低估和临时设置中进行FSO通信。由于潜在的照明和通信功能的整合，这项研究将为固态照明技术提供新的应用。其他影响领域包括：传感器网络，点对点网络利用方向覆盖协议，以及无人机/飞机空降网络和诸如空中飞机网络的军事无线应用程序。
