| + | Web service technology is a representative means of heterogeneous | ||
| + | system integration and communication. Process language standards, such as | ||
| + | WS-BPEL and WS-CDL, have accelerated the usability of web services in | ||
| + | business area. However, recently emerging web service devices in ubiquitous | ||
| + | environments still have a difficulty in coordinating their processes because of | ||
| + | the limited computing power and storage. This research proposes a framework | ||
| + | of event-based process enactment for ubiquitous web service devices. The | ||
| + | framework adopts P2P architecture where devices communicate with one | ||
| + | another via web services eventing. The schema of ECA rules and messaging | ||
| + | protocol are presented for P2P process enactment so that service devices can | ||
| + | interact each other and accomplish their process execution based on the ECA | ||
| + | rules. Our proposed framework is expected to be useful in ubiquitous service | ||
| + | environments since it enables a scalable and light-weighted process enactment | ||
| + | through event-based web service technology. | ||
