Abstract
Web services provide a successful way to communicate distributed applications, in a platform-independent and loosely coupled manner. Even though there are examples of good practice for the design, development, and management of web services, getting services to be context-aware is still under investigation. Current proposals require communication with an external context server or manager, slowing down service performance. In this work, the authors propose an architecture which utilizes complex event processing for detecting context events relevant to the services in question and an aspect-oriented adaptation, maintaining a loosely coupled service implementation as well as keeping its main functionality structure without adding any context-related intrusive code.
