Service elements and service templates for adaptive service composition in a ubiquitous computing environment

Service elements (SEs) and service templates (STs) are the basic elements for service-provision in a ubiquitous computing environment, which will be achieved by the new network technologies of peer-to-peer (P2P) and nomadic communication. An SE is a component for a service, and an ST is a design or flow-diagram of a service. In the ubiquitous computing environment, there are so many elements (SEs and STs) available that it is difficult to create services suitable for the users. Also, users require fully or well customized services. Thus, a new technology for providing autonomous service will need to be established. SEs and STs behave (move, combine, replicate, etc.) autonomously in the network and provide a suitable service for users and the situation. This paper describes SEs and STs and how STs are provided.
