Abstract
En el mundo actual en el que vivimos, se han extendido los entornos que trabajan con sistemas que garantizan el cumplimiento de tiempos de respuesta. Hasta ahora, al trabajar con entornos dinámicos, se aplicaba una aproximación clásica de diseño que nos aseguraba unas garantías temporales pero que podía implicar un gasto de recursos prohibitivo. Es por esto que se este dedicando un gran esfuerzo investigador para dotar de flexibilidad y dinamismo a sistemas de tiempo real. Este Proyecto Fin de Carrera estudia aquellos trabajos que buscan la aplicación de técnicas del mundo de la orientación a servicios a dichos sistemas. En concreto, algoritmos de composición de aplicaciones de tiempo real basados en servicios, centrándonos en dos algoritmos apropiados para dicha composición. Estos algoritmos se implementaron en el lenguaje de programación Matlab y su estudio condujo a la propuesta de mejora de los mismos. Finalmente, se desarrolló una herramienta en Matlab que permitía la simulación y validación de los distintos algoritmos. --------------------------------------------------------------------------------------------------------------------------------------------------------------------------
The current world we are living in, there has been an increase in the amount of application domains where the development of systems with temporal guarantees is required. Until now, when dynamic domains were used, a classic design approximation was implemented, which ensured us such temporal guarantees, but could entail a huge amount of resources expenses. It was this problem that led to a huge research effort aiming to give flexibility and dynamism to real time systems. This Master Thesis studies those researches which propose the use of service oriented techniques in this kind of real time systems. Being more specific, algorithms related to composition of real time applications based on services will be used, paying special attention specifically to two algorithms that are suitable for this scenario. These algorithms are implemented using Matlab's programming language. Their study has aided to propose an improvement of these algorithms. Finally, a Matlab application was developed for simulating and validating all the different algorithms.
