Résumé

Nowadays, we are witnessing a massive deployment of connected objects via the Internet of Things (IoT) in numerous fields. IoT can lead to a highly effective and significant contribution to the agricultural sector’s improvement. Once these IoT sensors are placed beneath the surface for water content and salinity measurements, they will need to communicate with the mobile operator’s base stations. However, electromagnetic propagation through soil is very different from propagation through the air because of the soil’s permittivity and electrical conductivity. This study relates more precisely to low consumption and large-scale deployment purposes. The simulations will be carried out for unlicensed frequency bands to assess the theoretical approach studied. We also outline the recent IoT applications in agriculture, the various protocols, and energy harvesting techniques for IoT that can be used in agricultural monitoring systems.
