SERVICE SELECTION BASED ON DOMINANT ROLE OF THE CHOREOGRAPHY

Web services are playing dominant role on Internet for e-business. The compositions of these services are
used to meet business objectives. The web service choreography describes the external observable behavior
of these compositions. Many compositions may available for same functionality. These compositions cannot
be distinguished on the basis of functional properties. This Quality of services (QoS) may help the user to
select web services and to analyze composition of the web services. Web service choreography is going to
dictate implementation of workflow. This workflow consists of several tasks. Each task is implemented by
web services. These services are hosted in large numbers by different service providers on different service
clusters. The mapping of service and task is difficult issue in run time environment. The interoperability
between services is also a great problem. The selection of services is very big issue.
In this paper we have proposed a bio-inspired selection algorithm based on dominant role and proposed a
discovery infrastructure. We have also used the client behavior to improve the failure of the composition of
the service.
