A Hierarchical Service Discovery Framework for Ubiquitous Computing

This paper presents a novel service discovery framework for ubiquitous computing called hierarchical ubiquitous computing service discovery framework (HUCSDF). HUCSDF offers a more flexible and scalable architecture which can combine the local services with remote services. Based on the novel architecture, HUCSDF possesses some useful characteristics such as supporting migration of user´s personal computing environment, group collaboration, interoperation with other kind of services and integration of context-aware information. These characteristics make HUCSDF different from many other service discovery frameworks and more adaptive to ubiquitous computing environments.
