Mechanism of Pricing Dynamically for Web Services

To promote application of web services in streamlining business-to-business or enterprise application integration, many researches on web services architecture, composition, and security have been done. However, pricing mechanism is necessary for commercialism of web services. Taking quality of service (QoS) and user experience into account, a QoS-driven dynamic web services pricing mechanism is put up in the paper, which makes services price vary dynamically with corresponding factors. Based on the mechanism, a simple prototype is developed. And then its architecture and pricing process is described. Experiments show that the web services pricing model works well and makes service price more reasonable and precise.
