Abstract

Importance of coordination among heterogeneous devices is significantly increasing to meet the challenges presented by the evolvement of the ubiquitous computing environment. The web services technology is going up as a promising solution to support the inter-operability between such heterogeneous devices via well-defined protocol. Currently, ECA(Event-Condition-Action) rule based framework for coordinating devices is proposed, it is called as WS-ECA(Web Services-ECA) framework. This framework was basically based on the web services and proposed the ECA based rule language, And this also proposed the framework that could enable the device coordination based on proposed rule language. In this paper, we propose the protocol among the components of WS-ECA framework to support dynamic feature for ubiquitous environment, and we also propose WSDL extension to support service and event descriptions these are provided in components of this framework.
