DESCRIPTION :
The OCOD ANR project, coordinated by INRAe and gathering Inria, University of Franche Comté and University of Clermont Ferrand aims to design and deploy a full wireless sensor network based system to sense, collect and assist different crop production in remote and hostile envrionenment. The system will be composed of a smart wireless sensor network to sense and collect efficiently the data. In rural remote regions, even with such a distributed wireless sensor networks, when the network is too sparse, there might have no end-to-end connectivity between the sensors and the central entity that needs to process data. An alternative way to collect data is thus to collect them from the air with the support of UAV (Unmanned Aerial Vehicles).
This project aims to investigate a new generation of data collection, combining intelligent wireless sensors and aerial means, and test this approach in agriculture, in particular in the test farm of INRAe in Auvergne. The main objective is to use unmanned aerial vehicles (commonly called "drone") as data mules to collect data from connected objects on the ground, in natural environments. This aerial solution will facilitate collections in hard-to-access natural environments, which can also suffer from signal attenuation with traditional communication networks. In this context, drones offer a large geographical zone of intervention, and are easier to deploy than land-based mobile vectors (e.g. ground vehicles). Compared to traditional sensor networks, this approach greatly lightens the hardware infrastructure to deploy, by avoiding the installation of numerous gateways to route information from the sensor nodes; gateways are expensive, energy intensive and require
regular maintenance, which is incompatible with their presence in an uneasily accessible natural environment.
In some cases, it is not possible for the drone to visit each terrestrial node, either for ground typology, energy efficiency (at the drone or at the ground wireless network level) or because of unexpected events?
The main objective of this project will be to design a dynamic multi hop data routing transmission able to dynamically convey data through the terrestrial sensor nodes towards a specific sink node that will be visited by the drone. This routing must take into consideration hardware and energy constraints by integrating for instance the capacity of the path to reduce data amount and be flexible enough to determine the best appropriate sink node.
Mission confiée
Within the OCOD project, the candidate will be in charge in the design and implementation of the drone-based adapted agricultural data collection for rural environment. He/she will participate to the OCOD project dynamic. He/She will also have to participate to the FUN team life.
Principales activités
The candidate will work jointly with INRAe and other project partners in order to learn about specificities of each crop that could be exploited. Collaborations could be extended with the Sencrop company with which the FUN team collaborate. All results will be validated experimentally, first on our lab testbed and then in real fields, both teams owning drones and wireless devices.
Timeline:
T0-T3: Review of adequate combined adapted routing and drone-assisted data collection
T4-T10: Investigation of a dynamic collect point selection integrating specificities of agricultural data
T0-T10: Handling of hardware and software already developed in both teams (parallel task)
T10-T15: Integration of dynamic collect point selection in a dynamic path planning approach for drones, implementation and validation
