关于使用能量收集实现无电池LoRaWAN通信的可行性研究

On the Feasibility of Battery-Less LoRaWAN Communications using Energy Harvesting

Carmen Delgado, Jos é María Sanz, Jeroen Famaey

AI总结:

本研究针对物联网电池更换问题,提出无电池LoRaWAN设备模型,分析电容器大小、电压阈值、传输间隔及能量收集速率对可靠性的影响,为无电池通信配置提供指导。

摘要:

从一开始,电池一直是物联网(IoT)的主要电源。然而,每年更换和处置数十亿个废弃电池在维护成本上高昂,且在生态上不负责任。由于电池是可持续物联网的最大威胁之一,无电池设备是解决此问题的方案。这些设备依靠使用各种形式的能量收集充电的长寿命电容器运行,导致设备间歇性开关行为。在本工作中,我们为LoRaWAN设备建模了这种间歇性无电池行为。该模型使我们能够表征性能,旨在确定LoRaWAN设备在何种条件下可以无电池工作,以及其参数应如何配置。结果表明,可靠性直接取决于设备配置(即电容器大小、开启电压阈值)、应用行为(即传输间隔、数据包大小)和环境条件(即能量收集速率)。

英文摘要:

From the outset, batteries have been the main power source for the Internet of Things (IoT). However, replacing and disposing of billions of dead batteries per year is costly in terms of maintenance and ecologically irresponsible. Since batteries are one of the greatest threats to a sustainable IoT, battery-less devices are the solution to this problem. These devices run on long-lived capacitors charged using various forms of energy harvesting, which results in intermittent on-off device behaviour. In this work, we model this intermittent battery-less behaviour for LoRaWAN devices. This model allows us to characterize the performance with the aim to determine under which conditions a LoRaWAN device can work without batteries, and how its parameters should be configured. Results show that the reliability directly depends on device configurations (i.e., capacitor size, turn-on voltage threshold), application behaviour (i.e., transmission interval, packet size) and environmental conditions (i.e., energy harvesting rate).
