Abstract

Abstract : Advances in wireless sensor technologies and MEMS have made it possible to automatically monitor the health status of dairy cows using Internet of things (IoT) and wireless body area networks. Since on‐cow measuring devices are energy constrained, a proper characterisation of the off‐body wireless channel between the on‐cow sensor nodes and the back‐end base station is required for an optimised deployment of these networks in barns. In this Letter, the long range (LoRa) off‐body wireless channel has been characterised at 868 MHz, a typical IoT frequency. Both path loss and temporal fading were investigated using LoRa motes. Based on this characterisation, network planning and energy consumption optimisation of the on‐body nodes could be performed, which enables the deployment of reliable dairy cow monitoring systems.
