A Flexible and Reliable Wireless Sensor Network Architecture for Precision Agriculture in a Tomato Greenhouse

Agriculture in the twenty-first century faces significant challenges given the ever-increasing need to produce more food to feed a growing population. Wireless Sensor Networks (WSNs) have recently emerged in agriculture to improve crop yields as well as to facilitate decision-making. Numerous environmental sensors that can sense data such as humidity, pressure, temperature, and light are deployed in the WSN that can be used both on land and underground. This paper proposes the design of a reliable and flexible WSN using heterogeneous environmental sensor data streams for precision agriculture in a tomato greenhouse. The proposed system is used to monitor the ever-changing greenhouse environmental conditions that will allow the farmer to have access to real-time as well as historical data of the greenhouse. Furthermore, the proposed system is evaluated using a qualitative approach. Finally, challenges and future works related to WSNs design for precision agriculture are explored.
