Mobile, pervasive computing environments respond to users' requirements by providing access to and composition of various services over networked devices. In such an …
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 processes in SOA are composed dynamically by services from different service providers. At run-time, some services may become faulty and cause a service …

In SOA, services may become volatile and fail to deliver the quality of service as requested by users. In this paper, we present an approach for repairing failed services by replacing …
When operating in volatile environments, service-based systems (SBSs) that are dynamically composed from component services must be monitored in order to guarantee …

A service-based system may require adaptation for several reasons, such as service evolution (eg, a new version may be available), hardware volatility (eg, network quality …
Big services are collections of interrelated web services across virtual and physical domains, processing Big Data. Existing service selection and composition algorithms fail to achieve …
This research addresses a critical issue of service level agreement (SLA) violation handling, ie, time constraint violation related to service-based systems (SBS). Whenever an SLA …
