With the exponential growth of communication and information technologies, adaptation has
gained a significant attention as it becomes a key feature of service-based systems, allowing …

Service-based systems that are dynamically composed at runtime to provide complex,
adaptive functionality are currently one of the main development paradigms in software …

Architecting software systems according to the service-oriented paradigm and designing
runtime self-adaptable systems are two relevant research areas in today's software …

Cloud applications built on service-oriented architectures generally integrate a number of
component services to fulfill certain application logic. The changing cloud environment …

Runtime adaptation is recognized as a viable way for a service-oriented system to meet QoS
requirements in its volatile operating environment. In this paper we propose a methodology …

Abstract Service-based applications have been attracting a lot of attention from both
academia and industry in recent years. Therefore, as these applications need to operate in a …

In recent years, many QoS-based web service selection methods have been proposed.
However, as QoS changes dynamically, the atomic services of a composite web service …

When operating in volatile environments, service-based systems (SBSs) that are
dynamically composed from component services must be monitored in order to guarantee …

Abstract The QoS attributes of Grid services play important roles in several tasks in Grid
computing such as QoS-aware service composition, service negotiation, resource …

Business processes consisting of component Web services are often executed in volatile
environments where the quality of service parameters of the participating services might …
