Service composition environments enable people to create, manage, share services, and compose atomic services. However, in such environments service responses might be very slow if users invoke services that are physically far from them since users and service entity hosts are always distributed in locations. This paper proposes the approach of dynamically controlling service invocations among service entity hosts based on the invocation request from users, and design several dynamic invocation control mechanisms to improve the response performance of services considering the service license constraints by service providers.
