Abstract
The Web Services-Event-Condition-Action (WS-ECA) framework is designed to enable
the heterogeneous communication devices in Ubiquitous Computing Environments to
achieve inter-operability via event-driven coordination.
Object-Process Methodology (OPM) is an integrated modeling method that unifies
the function, structure and behavior of a system. This paper presents specifying
a WS-ECA framework for ubiquitous web services in OPM. In addition, we propose
a dynamic conflict detection and resolution method in which dynamic conflicts are
detected by examining the post-conditions of services being triggered and are
resolved by acquiring user priority, service priority, and user’s service
preference.
