Universidad de Zaragoza (orcid)0000-0001-5316-8171 Real-time extensive livestock monitoring using lpwan smart wearable and infrastructure 2021 Access copy available to the general public Unrestricted Extensive unsupervised livestock farming is a habitual technique in many places around the globe. Animal release can be done for months, in large areas and with different species packing and behaving very differently. Nevertheless, the farmer’s needs are similar: where livestock is (and where has been) and how healthy they are. The geographical areas involved usually have difficult access with harsh orography and lack of communications infrastructure. This paper presents the design of a solution for extensive livestock monitoring in these areas. Our proposal is based in a wearable equipped with inertial sensors, global positioning system and wireless communications; and a Low-Power Wide Area Network infrastructure that can run with and without internet connection. Using adaptive analysis and data compression, we provide real-time monitoring and logging of cattle’s position and activities. Hardware and firmware design achieve very low energy consumption allowing months of battery life. We have thoroughly tested the devices in different laboratory setups and evaluated the system performance in real scenarios in the mountains and in the forest. info:eu-repo/grantAgreement/ES/DGA/T27-20R info:eu-repo/grantAgreement/ES/DGA/T59-20R info:eu-repo/grantAgreement/EUR/EC-FEADER/GCP2019004100 info:eu-repo/grantAgreement/ES/MICINN/PTQ2018-010045 info:eu-repo/grantAgreement/ES/MINECO/PTQ-17-09481 info:eu-repo/semantics/openAccess by http://creativecommons.org/licenses/by/3.0/es/ 2.838 2021 ENGINEERING, MULTIDISCIPLINARY 39 / 92 = 0.424 2021 Q2 T2 PHYSICS, APPLIED 76 / 161 = 0.472 2021 Q2 T2 MATERIALS SCIENCE, MULTIDISCIPLINARY 218 / 344 = 0.634 2021 Q3 T2 CHEMISTRY, MULTIDISCIPLINARY 100 / 179 = 0.559 2021 Q3 T2 0.507 2021 Engineering (miscellaneous) 2021 Q2 Computer Science Applications 2021 Q2 Process Chemistry and Technology 2021 Q2 Materials Science (miscellaneous) 2021 Q2 Fluid Flow and Transfer Processes 2021 Q2 3.7 2021 info:eu-repo/semantics/article info:eu-repo/semantics/publishedVersion Hermosa, A.
