An Aspect-Oriented Approach for Mobile Embedded Software Modeling

Recently, it is one of the most challenging fields in software engineering for embedded software development, since the advancement of embedded technologies has made our life increasingly depend on embedded systems and increased the size and complexity of embedded software. Embedded software developers must pay attention to not only performance and size but also extensibility and modifiability with a view to the complexity rising of embedded software. Besides, one of the characteristics of mobile embedded software is that they are context dependence with crosscutting concerns. Therefore, how to provide a systematic approach to modeling the mobile embedded software, especially on the crosscutting between the sensor, context and reactive behavior, has become an emerging issue in present researches. In this paper, we propose an aspect-oriented modeling process and notations extended from UML for mobile embedded software modeling to deal with the context dependence among sensors and their corresponding reactive functionalities. For the aspect oriented modeling process, the aspects modeling process is provided to separate the concerns of the mobile embedded software. Meanwhile, the extended notations with meta-model framework under class diagram, sequence diagram, and state machine diagram are depicted to facilitate the aspects modeling on structural and behavioral perspectives, respectively. Moreover, a Female Anti-Robbery System is used as an illustrative example to demonstrate our proposed approach.
