Embedded complex systems manufacturing becomes more and more a multidisciplinary problem. So complex systems, such as telecommunication systems, control systems, etc., must have a special simulation and validation process that mixes both analog and digital circuitry, collects all results from partials and specials simulations to be injected in behavioral models of all system components. Simulation results help us to take decisions; the strength of these decisions is a direct function of the validity of these results. Thus the need for efficient and valid simulation models is greater than ever. In this paper we describe some general behavioral models of element of wireless sensors network system, which let us to simulate the entire system in different use cases and all possible architectures using different protocols and technologies in an optimum time.
