ABSTRACT

The more mobile devices consuming web services, the more QoS-aware selection of mobile webservices, we need. A QoS(Quality of Service) contract is an agreement between the web service providerand the mobile user that specifies the level of the service quality. Web services users can be assured ofthe level of the service quality specified by the QoS contract. We propose a broker-based framework forQoS-aware mobile web services selection in this work. Under this architecture, the mobile users canrequest the web services through the service broker on the wireless networks. The service broker utilizesagents to monitor the web services quality and manages the service quality by notifying the service provider and mobile user of the service contract violation. Reliability, response time, and cost were themetrics used for QoS monitoring. Futhermore mobile users can select a web service best suited for his/herneeds through the service broker.
