A mediation service for Web Services provision in tactical disadvatnaged environment

The article describes Web services realization in a disadvantaged environment of the service oriented architecture (SOA) - based C4I tactical system that supports provision of situational awareness at the tactical level. In our work we propose a mediation service that interacts both with the producer and consumer of information, checks the quality of service (QoS) level of the service that can be offered by the network and accepted by producer and consumer. It adapts Web service realization to the client needs, and available network resources. The mediation service is also available in the service registry and can be discovered by the client requesting the adaptation. In the first part of the article we present the review of the methods of Web service realization in disadvantaged grids and provide justification of our work. In the second part we provide description of the mediation service operation. In the last part we provide primary verification of the service operation in assumed SOA tactical disadvantaged environment.
