In an effort towards designing a batteryless Internet of Things (IoT) sensor node that is powered by miniaturized energy-harvesting source(s), we combine the techniques of transient computing, approximate computing, data and energy predictions so as to handle the unpredictable power shortages of the miniaturized energy harvesting sources and reduce the overall power consumption of the IoT node. To evaluate the feasibility of our proposed approach, we build upon and extend an existing platform that consists of a peer-to-peer network (a sender node and a receiver node) where each of these nodes combines a Texas Instruments' FRAM-based micro-controller with a low cost, low power radio module and exchanging its data through SimpliciTI protocol. Our results illustrate that combining transient computing, approximate computing, data and energy predictions adds up their individual benefits to achieve an overall better utilization of the harvested energy of the node. Our results show that out of the total 60 transmissions that were due in an interval of 5 hours, for sending the temperature data from sender node to the receiver node every 5 minutes, a total of 32 transmissions were avoided, leading to a saving of more than 50% of the radio transmissions in the sender node. © 2020 IEEE.
