A Web Service Selection Mechanism Based on QoS Prediction

QoS evaluation plays a key role in QoS-based service selection.However,current QoS-based service selection methods haven't taken the dynamic nature of QoS into consideration and lack mechanisms to provide dynamic service performance prediction effectually.In this paper,propose a Web service selection mechanism which is based on QoS prediction.The architecture of QoS-prediction based service selection framework and the QoS prediction model are discussed in this paper in detail.
