유비쿼터스 프로세스 관리: 이벤트 기반의 서비스 프로세스 실현

Abstract

Process management technology can provide advanced services to end-users by racilitating service composition. Business process languages, such as WS-BPEL and WS-CDL, have increased the usability of web servisces through supporting procedural service composition in business area. Likewise ubiquious environments should also support service somposition capability for enhanced user experiences. However, ubiquious enbironments have difficulty in adopting the existing centralized process coordination methods mainly because of the limited computing power and storage capacity of devices and the instability of network connection. This paper proposes a nobel gramework for ubiquitous process management (uPM) that effectively supports event-based decentralized process enactmetn in ubiquitous environments. in the processes according th the ECA(Event-Condition-Action)reles assigned to each device. Specifically, a methdology for ubiquitous process enactment using web services-vased ECA rule schema and eventng message protocol is precented, and then illustrated through a home networking scenario. The proposed framework is expected to conribute ro user-entered network service composition by enabling implementation of lightweight process enactment based on web service technologies.
