In service composition environments, users and service entity hosts are always geometrically distributed. Therefore the performance of the service response might be poor when users invoke services that are physically far from them. Such issues are difficult to be solved with traditional caching technologies in the areas of contents delivery network because service providers do not always allow their service entities to be copied to all service entity hosts. In this paper, we deal with the service invocation control problem considering the above issues. First, we formally model the service invocation problem in service composition environments. Then we design several dynamic service invocation control mechanisms to improve the response performance of atomic services and composite services. The evaluation results show that (1) the mechanism for atomic services that considers both potential users for most service invocation requests and potential users for continuous requests can best improve the response performance
(2) the mechanism for composite services that considers the group characteristics of atomic services can improve the response performance more than other mechanisms
and (3) our proposed dynamic mechanisms can bring a stable response performance from the perspective of users.
