상황인지 컴퓨팅 환경에서 복합서비스를 제공하는 서비스시스템의 성능분석

Abstract

There are a variety of users and devices m a context-aware computing environment. In this environment, the service provided to a user may be the composition of diverse services rather than one independent service. Before user"s devices provide the composite service to the user, they should perceive user"s needs by gathering related information segments from other surrounding devices and/or sensors. We consider a context-aware computing environment providing composite and adapted service to users and propose an information processing model that characterizes the device where the collected data should be processed through services and/or aDplications. Based on this model, we provide an analytical tool to obtain some performance measures of the context-aware computing environment.
