An Empirical Energy Consumption Analysis in a Cattle Geolocation Device

In this work are presented detailed experimental energy consumption measurements of NB-IoT and GPS modules, aimed at implementing a cattle geolocation device. The objective is to combine modern low-power Internet of Things (IoT) protocols with IoT-assisted GPS location modes to allow implementing a cattle location device powered for years using a single primary battery. A data transmission energy consumption comparison is presented for NB-IoT with LoRa, as another state of the art low-power wide-area network protocol, and with GPRS, as a legacy network used for the Internet of Things, making it possible to observe the evolution of IoT networks for the agribusiness. Finally, a preliminary battery life estimation is presented.
