The emerging national healthcare information network (NHIN) is intended to improve the efficacy, efficiency, and safety of healthcare. At the same time. Service oriented architectures (SOAs) are rapidly becoming an accepted means of providing network information exchange across a heterogeneous fabric of node, and may be suitable for a next-generation NHIN-2s. Given the complexity NHIN and SOA due to multiple levels of system interactions, creating a valid and usable SoSE model for SOA application using a single technique that captures the desired level of details can be a daunting task. In this paper we give details of a hybrid approach to modeling and simulation of a specific SOA that is named MCSOA and has been configured for potential defense applications. Further, we show how MCSOA could be used to link low-comnmunications-capability healthcare data from sources like, the Alaska telemedicine testbed project (ATTP) to the proposed NHIN-2.
