Engineering pervasive services for legacy software

ArticleDescription: 1 archivo (312,6 KB)Subject(s): Online resources: Summary: In this paper we present a novel architectural approach to engineer applications that provide location-aware services; in particular, we explain how to extend existing software systems with location-aware services. We show how a clear separation of design concerns (e.g. applicative, context-specific, etc) helps to improve modularity. We stress that, by using dependency mecha- nisms among outstanding components, we can get rid of explicit rule-based expressions thus simplifying evolution and mainte- nance. We first motivate our research with a simple example. Next, we present the big picture of our architectural approach. Then we detail how to specify location-aware services; we present details of the services’ activation mechanisms. We finally we discuss some related work in the field. We conclude with some further issues in which we are now working.

In this paper we present a novel architectural approach to engineer applications that provide location-aware services; in particular, we explain how to extend existing software systems with location-aware services. We show how a clear separation of design concerns (e.g. applicative, context-specific, etc) helps to improve modularity. We stress that, by using dependency mecha- nisms among outstanding components, we can get rid of explicit rule-based expressions thus simplifying evolution and mainte- nance. We first motivate our research with a simple example. Next, we present the big picture of our architectural approach. Then we detail how to specify location-aware services; we present details of the services’ activation mechanisms. We finally we discuss some related work in the field. We conclude with some further issues in which we are now working.
