Semantic model for context — Aware service provision in disadvantaged network environment

The use of ontologies can facilitate many processes in C4I systems. They can be used to provide unambiguous description of data sent among systems as well as automate realization of services in dynamic NEC environment. The use of ontologies has been also proposed in the area of mobile computing, where the ability to react to dynamic changes of the environment with minimal human intervention is a fundamental requirement. A common element in the architecture of ubiquitous applications is a proxy, an element in charge of executing a number of content adaptations on behalf of one or several client applications running on mobile devices. These adaptations are triggered by specific conditions involving the mobile devices on which the applications execute. The article describes proposal of the semantic model for context - aware service provision in disadvantaged environment that is used to dynamically select adaptation actions performed on SOAP messages flowing from the service to the client entity.
