Web services on universal networks

The clients, in ubiquitous environment, want to be consistently offered services at any time and in any places. There are so many service discovery middleware such as Jini, UPnP and HAVi. Each one of them supports different communication protocol. Therefore, when the clients ask an inquiry of service search, they have to support communication protocol of all service discovery middleware. Namely, all the cost shall be borne by the customer. In addition, these middleware does not consider the service location and status. To solve these problems, we suggest the SOA-based framework is Web Services on Universal Networks. The framework supports a dynamic service discovery through the interoperability between service discovery middleware. Furthermore, it considers service location and status at service discovery process.
