Performance evaluation of edge-computing platforms for the prediction of low temperatures in agriculture using deep learning

Abstract

The Internet of Things (IoT) is driving the digital revolution. Almost all economic sectors are becoming "Smart" thanks to the analysis of data generated by IoT. This analysis is carried out by advance artificial intelligence (AI) techniques that provide insights never before imagined. The combination of both IoT and AI is giving rise to an emerging trend, called AIoT, which is opening up new paths to bring digitization into the new era. However, there is still a big gap between AI and IoT, which is basically in the computational power required by the former and the lack of computational resources offered by the latter. This is particularly true in rural IoT environments where the lack of connectivity (or low-bandwidth connections) and power supply forces the search for "efficient" alternatives to provide computational resources to IoT infrastructures without increasing power consumption. In this paper, we explore edge computing as a solution for bridging the gaps between AI and IoT in rural environment. We evaluate the training and inference stages of a deeplearning based precision agriculture application for frost prediction in modern Nvidia Jetson AGX Xavier in terms of performance and power consumption. Our experimental results reveal that cloud approaches are still a long way off in terms of performance, but the inclusion of GPUs in edge devices offers new opportunities for those scenarios where connectivity is still a challenge.

IoT in Smart Cities: A Survey of Technologies, Practices and Challenges

“…There have been some suggested methodologies for bringing fog processing for AI in smart agriculture, for, e.g., in [103] a deep learning entrusted to fog nodes (DLEFN) algorithm is described to support efficient use of resources and reduce cloud resource usage. However, as noted in [104], who use an edge system for temperature prediction using an LSTM, edge device performance still lacks that of similar cloud systems but the inclusion of DL capable hardware does provide opportunities for further innovations. Previous work by the same author [105], where they aimed to monitor crops for frost signs and trigger anti-frost measures, compared edge and cloud computing systems for outlier detection and determined that cloud implementations to provide much better performance.…”

The Design of University Physical Education Management Framework Based on Edge Computing and Data Analysis

“…These services usually require many mobile devices with limited size and low power consumption to perform computationally intensive and timesensitive tasks [26]. However, due to the low computing power and limited battery life of mobile devices, it is challenging to perform these services [27,28]. Edge computing is an advanced version of cloud computing that reduces latency by bringing the service closer to the end user.…”

Research on Data Optimization of CT System for Patients with Severe Pneumonia Based on Filtered Back Projection and Internet of Things

“…A schematic diagram of the filtered projection polar coordinate geometry is shown in Figure 3. It can be seen from the above formula that the projection length is no longer dependent on this angle, so the area to be solved for the image is transformed from the plane with XY as the horizontal and vertical coordinates to the polar coordinate plane with the length as the rotation angle [37]. In the process of CT image reconstruction, it is first converted from the XY coordinate domain to the polar coordinate domain and then reconstructed [38].…”
