In service-oriented computing, the vision is a market of services with alternative providers offering the same services with different cost and quality of service (QoS) properties, where applications form and adapt dynamically through dynamic service discovery and binding. To ensure decent and stable QoS to end users and efficient use of resources, it is required that both client applications and service implementations are able to adapt both their internal configuration and their binding to

In this paper we propose a solution based on the integration of an SLA mechanism into a compositional adaptation planning framework and describe a simple yet powerful implementation targeted for resource constrained mobile devices. As validation we include a case study based on a peer-to-peer distributed mobile application.
