INTRODUCTIONThe Internet of Things (IoT) has become one of the mostimportant branches of modern telecommunications. There aremany fields of application for this new paradigm: smart city,smart home, industry 4.0, precision agriculture. Animal healthmonitoring and tracking is a growing interest use case. Variousacademic and industrial projects exist for dairy herd healthmonitoring [1], [2] and wildlife animal tracking. The InriaFUN1 project team is collaborating with Stellenbosch Univer-sity in South Africa in the framework of the project LIRIMAPREDNET2. This project aims to develop a Wireless SensorNetwork (WSN) that is able to operate in sparsely populatedoutlying rural and wilderness areas, for efficient monitoringand protection of resources and ecosystems. In particular,the PREDNET project focuses on two specific use cases: 1)Jackal behavior understanding and cattle surveillance; 2) Fightagainst rhinoceros poaching. The proposed WSN containswearable devices carried by animals and infrastructure devices(base stations). The key requirements of the system are longrange transmissions and low power consumption. Indeed, theanimals could be spread over vast areas. Kruger NationalPark in South Africa (19485 km2) is the potential zone ofimplementation of the network. On the other hand, size andweight limitations of wearable devices must be respected,which limits the size and capacity of battery. Moreover, batteryreplacement is a difficult and expensive process. So, lowenergy consumption is essential to extend the network lifetime.Some animal tracking projects [3] use GSM to transmit col-lected data to ensure the coverage over a large area. However,high energy consumption of GSM and lack of coverage inthe deployment area do not meet the essential requirementsof the application. LoRa technology provides both long rangetransmissions and low power operation. This technology couldbe an appropriate solution for PREDNET project.II. RESULTSThe contributions of this work are multiple: 1) we definedcommunication parameters of LoRa radio for PREDNETWSN; 2) we performed radio propagation simulation forThis work is partially supported by a grant from CPER NPdC DATA andLIRIMA.1Self-Organizing Future Ubiquitous Networks; https://team.inria.fr/fun/2PREDator preventive ad-hoc NETwork; https://iww.inria.fr/prednet/en/chosen parameters to estimate the coverage area for bothurban and wilderness (rural) scenarios; 3) we confirmed thepropagation simulations with range tests; 4) we measuredexperimentally the Packet Error Rate (PER) of transmissions.The results of mentioned simulation and range tests for urbanscenario are presented in Fig. 1. For this scenario, the basestation node was installed on the roof of the EngineeringFaculty of Stellenbosch University and the mobile node was ina car. In the figure, colored area represents simulation resultsand colored squares correspond to range test measurementdata. As we can see, the simulation results fit with rangetests. Thus, used propagation model [4] as well as simulationparameters could be applied for other areas. The rural scenarioas well as measured PER values are not presented in this shortabstract paper because of page restriction. LoRa can providean efficient solution for low power communications in harshareas without telecommunication infrastructures.REFERENCES[1] E. Nadimi, R. Jrgensen, V. Blanes-Vidal, and S.
