Abstract
In a dynamic e-Business environment, constructing Virtual Society (VS) by creating Service cooperation has become the mainstream approach for reforming the development of application software systems. And e-contract is one of the important ways to support autonomic service cooperation. However, because of the inherent non-controllability of agents across different management domains, this approach has been confronted with the challenge of so-called trust crisis. This crisis has worried the research of autonomic computing and multi-agent systems for a long time. At the same time, with the growing popularity of autonomic service oriented cooperation, a general QoS support for services will play an important role for the success of this emerging technology. Unfortunately, current autonomic service cooperation does not offer comprehensive QoS support. In this paper, based on the previous work, we present a extended model for Trusted and Autonomic Service Cooperation integrated with QoS definition and management process, called TASC, which does not only eliminate the dilemma that the requirements of Autonomy and Trust conflict with each other, but also enable the QoS integration in Web services. It measures and monitors the QoS parameters, checks the agreed upon service levels, and reports violations to the authorized parties involved in the autonomic service cooperation management process.
