Extending Web Service Offerings Infrastructure (WSOI) for Management of Mobile/Embedded XML Web Services

摘要

Management of extensible markup language (XML) Web services executing in mobile and/or embedded environments poses new challenges coming from limited available resources and from the need for characteristic management activities, such as handling context sensitivity. We determined management requirements, studied relevant tradeoffs, and designed a management infrastructure for monitoring of mobile/embedded XML Web services. The infrastructure enables that some or all management activities are executed on a non-mobile/non-embedded gateway instead of a mobile/embedded provider Web service. Further, it contains support for managing context-sensitivity and for handling disruptions in quality of service (QoS) and intermittent connectivity. While our high-level architecture can be implemented upon several existing Web service management tools, we chose to develop a new version of our Web service offerings infrastructure (WSOI). The suggested solutions are being verified using the new WSOI prototype and validated on case studies, such as emulation of track-tracking Web services
