A policy framework for mobile web service customization

A web service in ubiquitous computing environments usually serves many consumers, with specific functional or nonfunctional requirements. Thus, web service should be customized and easy to be separated into semantic logic. In this paper, we present our research on mobile web service customization based on our previous work — SPBCA (Semantic Pattern-Based Context-Aware) Middleware. We exploit the tuple space technology to simplify the service lookup and locating. An approach is proposed to facilitate web service customization in ubiquitous computing environments. It uses a programmable way for the collaboration between service provider and consumer.
