Using Intelligent Proxies to Develop Self-Adaptive Service-Based Systems

Radu Calinescu, Yasmin Rafiq

Abstract: We present the theory underpinning the operation of a new tool-supported approach to engineering self-adaptive service-based systems (SBSs), and preliminary results from its evaluation in a telehealth case study. SBSs developed using our approach select their services dynamically, in order to maintain compliance with reliability requirements in the presence of changes in service behaviour. This adaptation is enabled by a new type of web service proxy called an intelligent proxy.
