Dependable Web Services Composition Method to Guarantee Response Time
Zhou Lina · Journal of Chinese Computer Systems · 2010
N-version programming provides an effective way to improve the dependability of Web services composition.But if the number of web services with same function is enormous,it will cause the time of Web services composition to increase greatly.With this problem in mind,a dependable Web services composition method based on grouping was proposed.The Web services with same function were divided into groups and the web service with the shortest response time was selected.Based on it,Web services composition was executed by using N-version programming.The simulation results showed that our method can not only ensure the dependability of Web services composition but also reduce the time for Web services composition.
