Advanced Shipboard Control Systems
Abstract
For the new millennium, the U.S. Navy has made a fundamental commitment to drastically reduced crew sizes. Automated systems can reduce crew size significantly, improving the efficiency and effectiveness of a ship. Automation must be continuously available and dependable under all conditions, including combat battle damage. To continue to work during the worst casualty conditions, command and control networks must automatically reconfigure around battle damage. By autonomously routing data around damaged components in an intelligent manner, network fragment healing dramatically improves distributed control system survivability. Dynamic reconfiguration, using network fragment healing, can provide the continuity of communications service that is required aboard U.S. Naval vessels during combat operations. To achieve survivable, distributed communication, an industry proven networking standard, ANSI-709.l Lon-Works, is extended to military applications. Specifically, the topology of a semi-mesh connection of rings is investigated through availability analysis. Hypercube and semi-mesh topologies are scalable. Furthermore, enhanced network fragment healing algorithms that route message traffic around damaged network components in a more efficient manner are investigated. In the future, these routing algorithms will be evaluated through network simulation, and validated with data obtained from network fragment healing tests performed aboard YP679, an Office of Naval Research test craft that is representative of a small scale combatant.
