A Management Infrastructure for Mobile/Embedded XML Web Services

The management of extensible markup language (XML) Web services executing in mobile and/or embedded environments poses new challenges that result from the limited availability of computing resources and from the need for characteristic management activities, such as handling context sensitivity. This paper briefly describes management requirements for and design of our management infrastructure for monitoring of mobile/embedded Web services. Its architecture is based on extending a SOAP engine with management modules, an approach adopted by several existing tools for monitoring non-mobile/non-embedded Web services. Apart for modules for management of non-mobile/non-embedded Web services, our infrastructure contains additional support for handling context sensitivity, disruptions in quality of service (QoS), and intermittent connectivity. We have been implementing the proof-of-concept prototype of this infrastructure as an extension of the Web service offerings infrastructure (WSOI)
