  1. Small Business Innovation Research A Distributed Cluster Based Architecture for ConstellationsWW Technology GroupEllicott City MD • INNOVATION • Software based infrastructure that facilitates dependable formation and operation of distributed real-time control systems. Several innovations advance the state of the art in distributed systems technology, including: (1) cold start algorithms for autonomous, dependable system organization and formation, (2) distributed on-line configuration control, monitoring and health assessment processes operating in concert across the entire system for coordinated system operation, (3) a multi-level scheduling approach, so distributed control elements will be responsive to local events and participate in system wide coordinated operations and (4) a robust fault/error model accounting for arbitrary fault/error cases and anomalies, thereby providing superior fault tolerance, particularly for Single Event Upsets. • ACCOMPLISHMENTS • Formulation of a System Organization Framework. • Production of a Baseline Use Case Analysis. • Production of a Distributed Fault Tolerant Element Discovery Protocol. • Implementation of a System Organization Prototype. COMMERCIALIZATION • Customers, including industry, already showing interest. • Industry needs architecture for robust multiple peer systems. • Flexible and extendable with multiple applications. • Critical roadmapstep for constellations and sensor webs. • GOVERNMENT/SCIENCE APPLICATIONS • Critical Enabling Technology for Distributed Spacecraft and key for dynamic formulation of Sensor Webs. • Infrastructure is key to discovering available nodes and initializing a group of distributed spacecraft or forming a sensor web. • Enables sensor webs to discover elements and form web autonomously. • Fits the GMSEC architecture and middleware paradigm.
