论文摘要
气候变化已被确定为对人类文明和可持续性的最关键威胁之一。产生大量碳排放的野火既是气候变化的驱动因素，也是气候变化的结果。早期，及时的野火检测系统可以将火灾限制为短和小型火灾，并大大减少碳。在本文中，我们建议通过利用卫星无处不在的全球覆盖范围来使用地面传感器部署和物联网（IoT）技术（IoT）技术进行野火检测。我们首先根据火火点火和检测模型制定最佳的物联网传感器放置策略。然后，我们分析了上行链路卫星通信预算和在窄带物联网（NB-iot）无线电接口下野火检测所需的带宽。最后，我们对加利福尼亚野火数据库进行模拟，并通过考虑减少碳排放和传感器/带宽成本来量化潜在的经济益处。
Climate change has been identified as one of the most critical threats to human civilization and sustainability. Wildfires, which produce huge amounts of carbon emission, are both drivers and results of climate change. An early and timely wildfire detection system can constrain fires to short and small ones and yield significant carbon reduction. In this paper, we propose to use ground sensor deployment and satellite Internet of Things (IoT) technologies for wildfire detection by taking advantage of satellites' ubiquitous global coverage. We first develop an optimal IoT sensor placement strategy based on fire ignition and detection models. Then, we analyze the uplink satellite communication budget and the bandwidth required for wildfire detection under the narrowband IoT (NB-IoT) radio interface. Finally, we conduct simulations on the California wildfire database and quantify the potential economical benefits by factoring in carbon emission reductions and sensor/bandwidth costs.
