An agent based approach to address QoS issues in service oriented applications

QoS is an issue of intrinsic importance in service oriented applications. Although many service oriented applications deliver their promised services yet it is rather difficult for them to maintain the QoS from user perspective. In this paper we develop an approach based on multi-agent system that helps to achieve the desired level of QoS by negotiating and coordinating between agents at the application layer. These service oriented applications may use the Web services of an agent based service in order to realize a service oriented architecture. In this paper, we propose an agent based approach to address QoS issues in service oriented applications. This approach is based on a unified framework that is applicable to both Web services and agent based services.
