CIDEA

https://cidea.hub.inrae.fr

The CIDEA project began in March 2022. It is being carried out by INRAE's TSCF research unit in partnership with LIMOS (Laboratoire d'Informatique, de Modélisation et d'Optimisation des Systèmes).

The first objective of the project was to develop communicating sensor nodes buried several tens of centimetres underground, and to optimise their operation in terms of energy consumption and communication range. The work then enabled the data transmitted by these sensors to be used in real time to adapt the behaviour of an agricultural robot passing nearby (e.g. changing its working speed and/or trajectory according to the soil moisture measured).

Today, the idea is to recover all the sensor data (e.g. soil moisture and temperature) from an aerial collection vehicle (drone). In the case of a large number of sensor nodes, the optimum collection trajectory for the drone is sought. Adjacent issues include (a) the limited and variable communication ranges of the sensor nodes, (b) the limited autonomy of the drone and obstacles in the environment, (c) being able to adapt the drone's trajectory in real time to ensure the quality of communications, and (d) minimising the energy consumption of the sensor nodes by getting as close as possible.
