可持续发展IoT中能量收集和数据传输的实际问题

Practical Issues of Energy Harvesting and Data Transmissions in Sustainable IoT

Yu Luo, Lina Pu

摘要:

可持续的物联网(IoT)正在成为绿色生活和智能产业的一个有前途的解决方案。在这篇文章中,我们调查的实际问题,在无线电能量收集和数据通信系统,通过广泛的现场实验。已经研究了能量收集电路和通信模块的许多重要特性,包括通信系统相对于传输功率的非线性能量消耗、与有效载荷相关联的唤醒时间以及在连续分组传输期间变化的系统功率。为了提高能量收集和能量利用的效率,我们提出了一种新的模型来准确描述可持续物联网设备的能量收集过程和功耗。使用商用物联网设备和RF能量采集器进行实验,以验证所提出的模型的准确性。实验结果表明,该模型与实际场景中可持续物联网设备的性能非常匹配。

英文摘要:

The sustainable Internet of Things (IoT) is becoming a promising solution for the green living and smart industries. In this article, we investigate the practical issues in the radio energy harvesting and data communication systems through extensive field experiments. A number of important characteristics of energy harvesting circuits and communication modules have been studied, including the non-linear energy consumption of the communication system relative to the transmission power, the wake-up time associated with the payload, and the varying system power during consecutive packet transmissions. In order to improve the efficiency of energy harvest and energy utilization, we propose a new model to accurately describe the energy harvesting process and the power consumption for sustainable IoT devices. Experiments are performed using commercial IoT devices and RF energy harvesters to verify the accuracy of the proposed model. The experiment results show that the new model matches the performance of sustainable IoT devices very well in the real scenario.
