Layered design approach for context-aware systems

The omnipresent integration of computer technology in everyday applications introduces new opportunities to make software systems aware of the context in which they are used. Such context-aware systems can respond more adequately to user expectations. However, modelling the context influence inside of software systems burdens developers for several reasons. First, context-dependent behaviour might crosscut the application logic of a software system. Next, since software systems can simultaneously reside in multiple contexts, context-dependent behaviour should be composable. Furthermore, since context information is volatile, these compositions are subject to change at runtime. This paper explores how layered design approaches can be used to deal with these specific characteristics.
