Consistent management of dynamic policies in distributed IoT applications The Internet of Things (IoT) allows to introduce in the internet world billions of new devices. Together with new exciting functionalities, IoT leads to new management challenges. We are in the context of a smart building, in which the principal services offered are controlled by IoT applications. These heterogeneous devices must be interconnected and must collaborate properly in order to provide services and support unexpected events or threats. One of the main goals of this thesis is to achieve a mechanism that controls the system behaviour through policies. But mostly, we research how to guarantee dynamic and consistent adaptation of these policies throughout a distributed system.
