Decentralized Approach for Distributed Service Environments

Universal service terminal (UST) has been proposed as a novel virtual distributed terminal supporting pervasive applications. It provides proactive services via aggregating diverse capabilities of devices around the user and auto-configuring them according to the capabilities, availability, user´s preference and application context, which results in always the best experience (ABE). The issues related to concept, architecture, design, and simulation are addressed and some basic procedures are introduced. Moreover, the results of simulation comparing two scenarios are given to validate the mechanisms designed in UST.
