In the Internet of Things (IoT), thousands of devices can be deployed to\nacquire data from the environment and provide service to several applications\nin different fields. In many cases, it is desirable that devices are\nself-sustainable in terms of energy. Therefore,the research community is\nexploring the possibility of employing battery-less devices, where the energy\nis derived solely from external and/or environmental sources, such as solar\npanels. In this work, we propose an ns-3 model of a (super) capacitor, which\ncan be used as the storage of the harvested energy in a battery-less IoT\ndevice, and add the support for the intermittent behavior of devices, turning\noff/on according to their energy level. To exemplify the use of the model, we\napply it to a LoRaWAN node, and compare the simulation outcomes with results in\nthe literature obtained with mathematical analysis, confirming the accuracy of\nthe implementation. Then, we show the importance of analyzing the interaction\nbetween energy availability and communication performance, paving the way for\nmore accurate and realistic simulations in the field. The implemented code is\nmade available as open source.\n
