SysML Extension by AADL Specification for WSN Modeling

International audience; In the area of software engineering and system architecture, the design and implementation process has taken a general methodological approach, encompassing all the activities necessary to design, evolve and verify a system providing an economical and efficient solution to needs of a client while satisfying all the stakeholders. For a long time, system engineers have used modeling techniques, the best known of which are AADL (Analysis and Architecture Design Language) and SysML (System Modeling Language). AADL was born as a language specific to the field focused on avionics and later was revised to represent and support a more general category of embedded systems in real time. SysML is an extension of the Unified Modeling Language (UML) to support engineering and modeling of the system. Based on these two languages and these two tools, several approaches have been created and developed to meet the needs and requirements of the system and also to overcome the problems and limitations of these two languages. In this paper, we will study and examine the two AADL and SysML modeling languages in a thorough way in order to extend the SysML language by the AADL language specifications for the modeling and design of sensor networks without (WSN).
