摘要

野火是世界上最具破坏性的自然灾害之一。本研究提出了一种创新的野火光通信系统(OWC),该系统利用先进的光学技术进行野火监测,并实现面向 5G 及以上(5GB)无线网络的无缝通信。通信节点之间的多输入多输出(MIMO)光链路是在考虑强度调制和直接检测(IM/DD)的情况下,按照开-关-密钥(OOK)方案,通过伽马-伽马(GG)分布设计的。在本研究中,通过分析得出了支持无人飞行器(UAV)的拟议 MIMO 链路的性能指标。针对提出的系统模型,研究了端到端 (E2E) 性能指标以及平均误码率 (ABER) 和中断概率 (Pout) 的新型闭式表达式。此外,还根据实际实验数据得出了仿真结果。本研究获得的结果提高了空间分辨率和精确度,从而能够在小规模野火的萌芽阶段通过通信进行探测。从本研究的进一步角度来看,所建议系统的开发有可能彻底改变野火预防和控制工作,对保护生态系统、社区和经济免受火灾的破坏性影响产生重大影响。

Revolutionizing Firefighting: UAV-Based Optical Communication Systems for Wildfires
Wildfires are one of the most devastating natural disasters in the world. This study proposes an innovative optical wildfire communication system (OWC) that leverages advanced optical technologies for wildfire monitoring and seamless communication towards the 5G and beyond (5GB) wireless networks. The multi-input–multi-output (MIMO) optical link among communication nodes is designed by gamma–gamma (GG) distribution under consideration of intensity modulation and direct-detection (IM/DD) following an on–off-keying (OOK) scheme. In this study, the performance metrics of the proposed MIMO link that enables unmanned aerial vehicles (UAVs) are analytically derived. The end-to-end (E2E) performance metrics and the novel closed-form expressions for the average BER (ABER) and outage probability (Pout) are investigated for the proposed system models. Furthermore, the simulation results are obtained based on the real experimental data. The obtained results in this study are improved spatial resolution and accuracy, enabling the detection by communication of even small-scale wildfires at their inception stages. In the further perspective of this research, the development of the proposed system holds the potential to revolutionize wildfire prevention and control efforts, making a substantial impact on safeguarding ecosystems, communities, and economies from the devastating effects of fires.

期刊介绍: Photonics (ISSN 2304-6732) aims at a fast turn around time for peer-reviewing manuscripts and producing accepted articles. The online-only and open access nature of the journal will allow for a speedy and wide circulation of your research as well as review articles. We aim at establishing Photonics as a leading venue for publishing high impact fundamental research but also applications of optics and photonics. The journal particularly welcomes both theoretical (simulation) and experimental research. Our aim is to encourage scientists to publish their experimental and theoretical results in as much detail as possible. There is no restriction on the length of the papers. The full experimental details must be provided so that the results can be reproduced. Electronic files and software regarding the full details of the calculation and experimental procedure, if unable to be published in a normal way, can be deposited as supplementary material.
