论文摘要
可持续的物联网（IoT）正在成为绿色生活和智能产业的有前途的解决方案。在本文中，我们通过广泛的现场实验研究了无线电收集和数据通信系统中的实际问题。已经研究了能源收集电路和通信模块的许多重要特征，包括相对于传输功率的通信系统的非线性能源消耗，与有效载荷相关的唤醒时间以及连续数据包传输过程中的变化系统功率。为了提高能源收获和能源利用的效率，我们提出了一个新模型，以准确描述能源收集过程和可持续IoT设备的功耗。使用商业物联网设备和RF能量收割机进行实验，以验证所提出模型的准确性。实验结果表明，新模型在实际情况下非常匹配可持续IoT设备的性能。
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.
