Title:

Practical Precision Agriculture with LoRa based Wireless Sensor Networks

Authors:

Jonathan Gresl, Scott Fazackerley and Ramon Lawrence

Abstract: Precision agriculture is enabled by using real-time data to manage environmental variations, measure performance to improve upon previous seasons, and perform predictive analysis to make better growing decisions, resulting in higher production yields with lower production costs. Although beneficial, collecting and analyzing the environmental data is an expensive and complicated endeavor. Numerous existing wireless sensor network (WSN) solutions rely on protocols such as 802.15.4 b (LR-WPANs) and 802.11x (WLAN) but provide limited transmission range, complex communication stacks and data management, and high power consumption. Additionally, many existing services introduce challenges with data ownership and residency. These factors present a high barrier to entry for growers. The resources required to implement and maintain sensor networks are too high to justify the investment. This work presents an approach that uses inexpensive and effective hardware that is easily setup and maintained. Costs to implement the network are reduced through the use of open-source hardware. Transmission ranges and power consumption are improved by using long range (LoRa) radio transceivers. By addressing these limitations, growers will be better enabled to adopt new technologies, ultimately improving sustainability, viability, quality and profit margins in agriculture.

Title:

A Modified MPRR Protocol for WSN in Agricultural Scenario

Authors:

Marco Cagnetti, Mariagrazia Leccisi and Fabio Leccese

Abstract: This paper analyses the use of a WSN for agricultural scenario, referencing to the modality of communication between the network nodes, and proposes a modified version of Multipath Ring Routing (MPRR) to improve performances and robustness of the network on the long period. Through simulations with Castalia, some limits of the standard MPRR have been highlighted, and through the possibility to modify the algorithm itself, improvements have been made that make the modified MPRR suitable for our scenario.

Title:

Advances in Sensing Technologies for Smart Monitoring in Precise Agriculture

Authors:

Luca Maiolo and Davide Polese

Abstract: The demand for a continuous increment of crop production reducing at the same time the impact on the used resources is a challenge that can be solved only exploiting the full potential of sensors technology applied in precise agriculture. In this review, we present the most recent advances in remote sensing technologies to be deployed in field and in greenhouses to monitor multiple key parameters such as air temperature, solar radiation, vegetative index, plant microclimate, soil feature, etc.

Title:

Smart Farming in sub-Saharan Africa: Challenges and Opportunities

Authors:

Pamela Abbott, Alessandro Checco and Davide Polese

Abstract: Smallholder farmers provide the majority of food production in sub-Saharan Africa. They will be severely impacted by climate change, especially because they are dependent on rain-fed irrigation. We provide a summary of challenges and opportunities in designing smart farming infrastructure in this context. We observe that innovation in technology and knowledge production is necessary to increase the efficacy of water usage and land management. Such solutions must take into account the technological constraints and their regional variability to be able to provide sustainable and scalable solutions. Such solutions also need to embrace the notion of openness, encouraging collaborative endeavour and avoiding proprietary implementations.
