The Research of Web Service Selection Based on the Ant Colony Algorithm

The Web service composition is one of the most important ways to satisfy the users´ personalized requirements and supply the high quality service for users, and the foundation of service composition is the selection of Web service. Firstly, expounded the basic principle of Ant Colony Algorithm and analyzed the model of Web service selection and brought the algorithm into the fields of Web service selection and transformed the problem of Web service selection based on the QoS into the problem of finding the optimization path. Secondly, given the steps for solving the problem of Web service selection based on the Ant Colony Algorithm and contrasted the results under different parameters. At last, used the virtual scene, the author tested the validity of Ant Colony Algorithm in solving the problem of Web Service selection.
