Dynamic web services discovery based on client QoS feedback
Qi Chen · Jisuanji gongcheng yu sheji · 2011
The traditional Web service discovery mechanism that is based on keywords and simple classification can not satisfy users’ requirements due to the lack of quality of service(QoS).With this problem in mind,a QoS-based Web service discovery model is proposed.In order to support QoS-based Web Services discovery,the QoS broker mechanism is introduced into the traditional web service discovery model,which quantifies and measures the QoS information of users’feedback after they used the web services.On the basis of these,according to the characteristics of dynamic nature of web services and QoS requirements of different users,an approach is described to measure the QoS data based on users’feedback.A QoS-based web service discovery algorithm is also proposed.The experimental results show that the web service discovery methods meet the needs of users better.
