Web service composition using PSO — ACO

Web services are constructed to build the electronic business application to provide flexibility and interconnection of different applications using the internet. When a user can not satisfied any individual service then in order to satisfy the need of user request service, composition is performed to compose the available services. When there are different web services available then we need a suitable method to perform the composition of services depending upon the quality of service parameters. In our proposed work, we tried to compose the web service with maximum overall QoS valuesaccording to the user's queries. To solve the service composition, we applied quality of service (QoS) parameters, a combination of particle swarm optimization (PSO) and ant colony optimization (ACO) algorithms for service composition.
