Abstract : The Service-Oriented Architecture (SOA) paradigm has been chosen by NC3B as the recommended method to achieve interoperability at the information infrastructure level within NATO. Current technologies to implement SOA were designed for civilian use over robust, high-bandwidth networks and consequently not designed to work over the disadvantaged grids that are employed at the military tactical level. This makes it hard to achieve interoperability among the Nations in the battle space. The disadvantaged grids that IST-090 considered are mobile ad-hoc networks that are characterized by line-of-sight connections, low bandwidth, intermittent availability, etcetera. IST-090 identified improvements to make SOA work while using disadvantaged grids and built demonstrations that show how the challenges that arise because of the use of disadvantaged grids in near-real-time, as is the case at the tactical level in military operations, can be mitigated. IST-090 used a concrete military scenario as a global context for the study. Areas of research included: efficient communication frameworks, mechanisms to reduce needed bandwidth and mechanisms to improve reliability. IST-090 specifically considered the following technologies: Web Services and Service Discovery, Data Distribution Services, Common Distributed Databases and Cross-layer design. The results demonstrated that SOA can be applied at lower levels than previously thought.
