This Phase II SBIR project demonstrated efficient and effective agent-based services for military communities of interest (COI) operating on network-centric architectures. Building on the commercial world concept of the enterprise service bus (ESB), the agent-based services (ABS) architecture defines a data-centric framework for efficient utilization of all available assets in network-centric applications. Software agents on the architecture 1) organize all available information into COI-specific knowledge domains (using common, extensible, commercially supported, and standards-based formats), 2) provide translation and brokering services for individual systems, and 3) provide local and remote end-users with relevant, customized products (e.g., fused visualizations). The ABS architecture has guided the development of several COI-specific implementations, including the agent-based Theater Undersea Warfare Initiative (TUSWI) Non-Gaussian Data Fusion System (NGDFS) Web Service (TNGWS) that utilizes sophisticated legacy data fusion and resource optimization algorithms, running on a Linux cluster at the Maui High-Performance Computing Center (MHPCC), to provide recommended asset allocations, search effectiveness maps, and location estimates for high-interest targets to the Theater Undersea Warfare Initiative (TUSWI) system in the Pacific. Additional ABS implementations include support for distributed search planning at the NASA missile test facility at Wallops Island, VA, and agent-based data fusion for the SQQ-89 Improved Performance Sonar (IPS) Data Fusion Functional Segment (DFFS).
