Time Ordering Architecture in SCA

In this work we extend SCA models with timing restrictions to capture the behavior of systems where time determines the correctness of the implementation. Furthermore, we establish a translation from this extended model in the timed automata formal model. In this case, we have considered the timed automata formalism supported by the UPPAAL tool, due to the model-checking techniques that we can apply by using it. To illustrate the extension of the SCA model and the translation process, we have chosen a roaming service system that shows the utility of our proposal in the mobile commerce area.
