A CORBA Trader-based Dynamic Binding Infrastructure in Pervasive Computing

Pervasive computing environments are far more dynamic and heterogeneous than enterprise environments, in which, the computing is invisible for users, but they may still enjoy its services perfectly. In order to realize this stirring idea, the system needs to automatically discover, use the devices and services. The paper introduces A CORBA trader-based dynamic binding infrastructure called CTDBI that automatically deals with issues of service discovery and binding. The CTDBI mask the dynamic and heterogeneous environment, and provide constant available services to application through uniform interface. By providing robust separation of concerns to applications, it can simplify the implementation of application in pervasive computing. It also uses a contextual approach to improve the efficiency of discovery mechanism. Finally, we have presented detailed examples to evaluate the validity of CTDBI
