|Internet of things (connected objects)|
Gradually, connected objects will be used in all economic sectors (industry, health, sales, etc.). For example, the use of connected sensors communicating data on the state of the rail network in real time (state of the catenaries, temperature of the rails, etc.) will soon enable the SNCF to predict the maintenance operations to be performed. Connected objects therefore are very promising. Nevertheless, they pose significant technological and societal challenges.
