Smart Farming System Based on Fog Computing and LoRa Technology

Nowadays, the increased agricultural production at a lower cost is more and more driven by the Internet of Things (IoT) and the cloud computing paradigms. Many researches and projects have been elaborated so far in this context. It aims at reducing human efforts as well as resources and power consumption. Such projects are mainly based on collecting various data pertaining to the agricultural area and sending it to the cloud for further analysis. However, the long distance between sensors/actuators and the cloud leads to a significant increase in latency, which leads to a decrease of performances of the irrigation systems, pesticide monitoring, etc. This paper presents an alternative solution based on Fog Nodes and LoRa technology to optimize the number of nodes deployment in smart farms. Our proposed solution reduces the total latency induced during data transmission toward the cloud for processing.
