摘要:

由于全球野火的严重性和频率增加,野火管理和检测的挑战最近越来越受到关注。流行的火灾探测技术,如卫星成像和基于遥感相机的传感技术,存在探测时间晚、可靠性低的问题,而早期野火探测是防止大规模火灾的关键。在本文中,我们提出了一种新的基于无人机辅助物联网(UAV-IoT)网络的野火检测解决方案。主要目标是(1)研究用于野火检测的UAV-IoT网络的性能和可靠性,以及(2)提出优化UAV-IoT网络的指导方针,以在有限的预算下提高火灾检测概率。我们专注于优化物联网设备的密度和覆盖森林区域的无人机数量,以便在有限的时间和预算内最大限度地提高野火检测概率的下限。在火灾发生后的任何时候,距离火灾有限距离内的物联网设备都可以检测到火灾。只有当无人机在附近时,这些物联网设备才能报告它们的测量结果。离散时间马尔可夫链(DTMC)分析被用来计算在离散时间的火灾探测概率。在宣布火灾检测之前,验证状态被设计为考虑物联网设备的实际限制,例如误检和误报概率。数值结果表明,如果有足够的系统预算,基于UAV-IoT的火灾探测可以提供比最先进的卫星成像技术更快,更可靠的野火探测解决方案。

英文摘要:

The challenge of wildfire management and detection is recently gaining increased attention due to the increased severity and frequency of wildfires worldwide. Popular fire detection techniques such as satellite imaging and remote camera-based sensing suffer from late detection and low reliability while early wildfire detection is a key to prevent massive fires. In this paper, we propose a novel wildfire detection solution based on unmanned aerial vehicles assisted Internet of things (UAV-IoT) networks. The main objective is to (1) study the performance and reliability of the UAV-IoT networks for wildfire detection and (2) present a guideline to optimize the UAV-IoT network to improve fire detection probability under limited budgets. We focus on optimizing the IoT devices' density and number of UAVs covering the forest area such that a lower bound of the wildfires detection probability is maximized within a limited time and budget. At any time after the fire ignition, the IoT devices within a limited distance from the fire can detect it. These IoT devices can then report their measurements only when the UAV is nearby. Discrete-time Markov chain (DTMC) analysis is utilized to compute the fire detection probability at discrete time. Before declaring fire detection, a validation state is designed to account for IoT devices' practical limitations such as miss-detection and false alarm probabilities. Numerical results suggest that given enough system budget, the UAV-IoT based fire detection can offer a faster and more reliable wildfire detection solution than the state of the art satellite imaging techniques.
