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.
