Abstract : The increasing size and complexity of distributed systems create a need to raise the level of abstraction for their development. This need becomes critical for pervasive computing where non-functional properties, such as security, must be guaranteed. Architecture description languages (ADLs) propose a promising approach to coping with the size and complexity of pervasive computing systems. A system is defined by a high-level description that may be used to produce a programming framework. However, non-functional properties are not specifically addressed by existing ADL works. To address this issue aspect-oriented programming is a well-proven technique to properly modularize non-functional concerns that can be dealt with by weaving dedicated code into a program. In this paper, we present DiaAspect, an aspect-oriented language for our ADL, DiaSpec. Like most ADLs, DiaSpec exposes features enabling an accurate coordination of aspects. We demonstrate the expressiveness of DiaAspect with two examples of security policies in pervasive computing. We also show how, combining the knowledge of the architecture description with aspect code, improves aspect weaving in the implementation code.
