To address the problem of service composition in pervasive computing, and to provide the IGRS ubiquitous devices the abilities of inter-operation and cooperation, we design the UDIO, a middleware of dynamic service composition based on IGRS protocol. In this paper, the system architecture of UIDO, as well as a matrix-based path-finding algorithm for service composition, are introduced which prove...
Today's Web has provided an infrastructure to build applications that can utilize the Web services standards for developing and deploying services in heterogeneous environments. However the current Web at its current stage lacks the capability of understanding the context in which a particular service has been requested. Therefore we assume that providing semantic annotations through the use of ontologies...
Recent years have seen a proliferation of work on the Semantic Web, an initiative to enable intelligent agents to reason about and utilize World Wide Web content and services. Concurrently, the networking community has developed a concept of the knowledge plane, using artificial intelligence to reason about and manage network behavior. These two efforts have progressed independently despite potential...
Current fashion systems to interconnect large software architectures are moving toward SOA based solutions. This new paradigm for designing system can be improved, in our opinion, by using semantics. Semantics can a play a main role in boosting interoperability thanks to current technologies to express knowledge and to describe semantic Web services (SWS). This paper tackles the provision of a Software...
