摘要：
In service oriented environments, complex applications can be constructed from invoking a number of atomic service components Given that many services provide the same functionality and differ in quality of service (QoS). e g. availability and execution time, the critical challenge in service composition is to dynamically identify the available service components to meet the user's QoS requirements and preference In this paper, we propose to tackle this challenge through incorporating the negotiation mechanism into service composition The negotiation mechanism allows for both service consumers and providers to exchange proposals and counter proposals to reach agreements on QoS attributes dynamically at runtime
