| 摘 要： | IntroductionService oriented computing is rapidly adoptedas a popular paradigm for the development of dis-tributed applications.In Grid environments,allare treated as services,which include computation-al resources,storage resources,networks,pro-grams,databases,and so on1].A service-orientedparadigm describes an application in terms of whatfunctionalities(services)it can exploit instead ofwhich objects are involved.In general,serviceproviders independently develop their Grid ser-vices,and so…

| Abstract: | This paper aims to present a role-based interaction model for dynamic service composition in Grid environments. Assigning roles to a service means to associate with it capabilities that describes all the operations the service intends to perform. When all of the services can be recognized by their roles, the appropriate services can be selected. Based on the interaction policy, a role-based interaction model not only facilitates access control, but also offers flexible interaction mechanism for adapting service-oriented applications. This interaction model adopts programmable reactive tuple space to facilitate context-dependent coordination. |
