===== 
For a long time, the IoT (Internet Of Things) or Cyber Physical Systems (CPS) were only considered to build systems for data acquisition from sensor networks in order to proceed to data mining for example. However, IoT systems are also able to interact on their environment by actuators. One of the major problems in
this case is the management of concurrent access conflicts with these actuators, especially in the application composition phase for IoT where the development of these applications is carried out independently. The goal is to identify all convict in these large-scale IoT systems with a divide-and-conquer approach to
provide compliant applications (not leading to inconsistencies in environmental actions). The goal is therefore to provide tools to identify conflict (actuation conflict) in IoT applications whose semantics are unknown and how we will solve them before deployment. In order to carry out this identification as early as the design phase, it is necessary to define conceptual models (logical aspects), operational models (behavioural aspect) and implementation models of embedded synchronous Finite State Machine (FSM) in IoT applications. If the logical models are validated by model checking, the use of the simulation at the implementation models level makes it possible to validate the properties already validated on the logical model. It also allows to propose asynchronous execution machine strategies taking into account any emerging conflicts in the composition of IoT applications. The DEVS (Discrete-Event system Specification) formalism allows an automatic simulation of synchronous and asynchronous FSM in a unified and formal framework. 

During these two days’ workshop we discuss a new approach to manage the conflict of actuators in IoT systems from DEVS simulation models defined early in the design phase of IoT applications. This approach consists in: (i) DEVS modelling of the IoT system (synchronous FSM) with its execution machine (asynchronous FSM); (ii) defining a new DEVS ACM (Actuation Conflict Manager) model that integrates strategies to resolve concurrent access conflicts from actuators; (iii) simulating strategies from input test sets to validate the possible strategy to apply in case of conflict; (iv) integrating the selected strategy into the IoT system to make it compliant.

We also discuss the best way to generate as relevant as possible test sets using some new approaches like evolutionary algorithms.
