Software applications are continuing to grow at a rapid pace and became more and more complex. Thus, the use of software architectures in the development process is the ideal solution to deal with this issue. In this context, many Architecture Description Languages (ADLs) have been introduced to define the software architecture and its elements. Most of these ADLs do not address the dynamic behavior of the software architecture. This dynamic behavior is most commonly known as architectural reconfiguration. In our work, we use the Architecture Analysis and Design Language (AADL) due to its capacity to represent the architectural reconfiguration. However, AADL suffers from the absence of a concrete model to define its formal semantics. This paper presents a formal approach based on Bigraphical Reactive Systems (BRS) to model the dynamic architectural reconfiguration of embedded real-time systems expressed in AADL.
