A Multi-Criteria QoS-aware Trust Service Composition Algorithm in Cloud Computing Environments

Weina Lu Xiaohui Hu Shangguang Wang and Xiaotao Li

Firstly, statistical test is employed to remove the uncertain outliers and to estimate the ideal value of the collected objective QoS data. Secondly, subjective QoS evaluations of providers and users are aggregated according to direct trust and recommended trust. Finally, services are composed through global QoS optimization. Experiments for each stage show that the approach improves the accuracy and precision of service composition.
