In this paper, we describe our experiment and demonstration in applying Service Oriented Architecture (SOA) to mobile nodes in the tactical domain. Our scenario encompasses two convoys that exchange information using NATO standards in order to achieve Friendly Force Tracking between different nations. NATO has identified the WS-Notification standard for the publish/subscribe pattern, so we use that as our messaging middleware to convey NATO Friendly Force Information (NFFI) data. We use a hybrid setup consisting of real nodes using Wireless Broadband Mobile Networks (WBMN) for one convoy and emulated nodes using the Common Open Research Emulator (CORE). The experiments involved components provided by nations participating in the NATO research task group (RTG) IST-RTG-118 “SOA recommendations for disadvantaged grids in the tactical domain”. The group addresses the challenge of implementing the SOA paradigm at the tactical level by providing guidance and best practices. In our work we provide empirical results from our work on publish/subscribe, and give recommendations as to the applicability of the standard in the tactical domain.
