While new network technologies bring ubiquitous-computing environments ever closer, methods to provide suitable services within such environments remain immature. We describe the ubiquitous service-oriented network (USON) architecture, a new service-provision architecture, covering the basic concept, components and their roles, and the service-provision mechanism. A USON provides services in two phases, a service-composition phase in which service elements (SEs) are combined on the basis of service templates (STs), and a service-emergence phase in which a new ST is obtained on the basis of the history of usage of SEs and STs. A USON can handle various types of SEs, representing Web services, computer resources, and sensor devices. The establishment of USON technologies on networks provides various services within ubiquitous-computing environments.
