They are equipped with high performance inertial measurement units (IMU) and absolute positioning systems analyzing user's movements, but they can easily be diverted to analyze likewise the behaviors of domestic animals such as cattle. Using smartphones to study animal behavior requires the improvement of the autonomy to allow the acquisition of many variables at a high frequency over long periods of time on a large number of individuals for their further processing through various models and decision-making tools. Indeed, storing, treating data at the iPhone level with an optimal consumption of energy to maximize battery life was achieved by using edge computing on the iPhone. This processing reduced the size of the raw data by 42% on average by eliminating redundancies. The decrease in sampling frequency, the selection of the most important variables and postponing calculations to the cloud allowed also an increase in battery life by reducing of amount of data to transmit. In all these use cases, the lambda architectures were used to ingest streaming time series data from the Internet of Things. Cattle, farm animals' behavior consumes relevant data from Inertial Measurement Unit (IMU) transmitted or locally stored on the device. Data are discharged offline and then ingested by batch processing of the Lambda Architecture.

More and more devices capable of interacting with each other are being designed and appearing on the market. Learning about IoT technologies is becoming inevitable in education. In this article, we propose a demonstrator to learn, through use cases, the essential concepts of IoT applied to Smart Homes. From basic use cases implemented in a model building, the general public can more easily understand the operating principles of these new applications, which opens the door to the imagination of new ones.

The Internet of Things (IoT) and the availability of microcontrollers and sensors with low data rates and long ranges, as well as low-power wide area networks (LPWANs), allow for much more advanced monitoring systems.

This data must be processed very quickly, especially for the systems that need to make real-time decisions. The Kappa architecture provides a way to process Agriculture 4.0 data at high speed in the cloud, and thus meets processing requirements. This paper presents an optimized version of the Kappa architecture allowing fast and efficient data management in Agriculture. The goal of this optimized version of the classical Kappa architecture is to improve memory management and processing speed. the Kappa architecture parameters are fine tuned in order to process data from a concrete use case. The results of this work have shown th e impact of parameters tweaking on the speed of treatment. We have also proven that the combination of Apache Samza with Apache Druid offers the better performances.

The transfer of this data to the cloud is a challenging problem because of the congestion at the network level, and therefore processing time could be too long when we use a pure cloud computing strategy. On the other hand, new applications requiring the processing of large amounts of data in real time have gradually emerged, such as virtual reality and augmented reality. These new applications have gradually won over users and developed a demand for near real-time interaction of their applications, which has completely called into question the way we process and store data. To address these two problems of congestion and computing time, edge architecture has emerged with the goal of processing data as close as possible to users, and to ensure privacy protection and responsiveness in real-time. With the continuous increase in computing power, amounts of memory and data storage at the level of smartphone and connected objects, it is now possible to process data as close as possible to sensors or directly on users devices. The coupling of these two types of processing as close as possible to the data and to the user opens up new perspectives in terms of services. In this paper, we present a new distributed edge architecture aiming to process and store Internet of Things and multimedia data close to the data producer, offering fast response time (closer to real time) in order to meet the demands of modern applications. To do this, the processing at the level of the producers of data collaborate with the processing ready for the users, establishing a new paradigm of short supply circuit for data transmission inspired of short supply chains in agriculture. The removing of unnecessary intermediaries between the producer and the consumer of the data improves efficiency. We named this new paradigm the Short Supply Circuit Internet of Things (SSCIoT).

Ces modifications du régime hydrique nous amènent à devoir reconsidérer nos modes de productions agricoles et à optimiser la gestion de l’eau. La raréfaction des ressources et l’augmentation des besoins industriels en matière de productions agricoles et alimentaires (liés à l’augmentation de la population mondiale) impliquent un besoin d’optimiser l’utilisation des engrais et des produits phytosanitaires.

Cette zone est caracterisee par des regimes pluviometriques irreguliers qui ont une influence considerable sur les pertes en sol. Dans les zones montagneuses, les phenomenes d’erosion hydriques sont accentues par les fortes pentes et la couverture du sol reduite. Les barrages alimentes par ces zones subissent un envasement lie a une erosion importante. L’envasement de ces barrages limite drastiquement leur capacite et donc leur duree d’exploitation. Lorsqu’ils sont utilises pour la recharge de nappes phreatiques, les lâchers entrainent des particules fines remises en suspension qui s’accumulent au niveau des zones de recharge et reduisent la capacite d’infiltration par colmatage de la porosite du sol, ce qui conduit a un abattement important des niveaux piezometriques.

In addition, a web interface for encoding behavior observed on videos allows to synchronize the observations with the measurements.
