Numerous Iot Applications now manage connected objects, not restricted anymore to collect data from field, but having the capacity to act on their surrounding environment.

Thereby, large scale IoT systems, become critical. Continuous deployment and integration solutions (DevOps) require new tools for enforcing the operational security and the degree of validation of the applications.

• Challenge 1. IoT software composition lies on shared hardware/software services. Concurrent accesses to these services lead deployed software applications to behave in a non-deterministic fashion. Synchronous languages offer a formal approach to constrain accesses and validate the deterministic behavior of the applications and the services.
• Challenge 2. Meanwhile, DEVS formalism provides capabilities to model and simulate discrete, continuous or hybrid complex systems, hence allowing:
  • To model complex physical interactions between actuators through a real physical environment (e.g. heater/cooler)
  • To model asynchronous software components to verify some properties through tests and simulations (case applicable to the modeling of the execution machine of a FSM)
