SCARS: Scalable Self-Configurable Architecture for Reusable Space Systems

Creating an environment of ldquono doubtrdquo for mission success is essential to most critical embedded applications. With reconfigurable devices such as field programmable gate arrays (FPGAs), designers are provided with a seductive tool to use as a basis for sophisticated but highly reliable platforms. We propose a two-level self-healing methodology for increasing the probability of success in critical missions. Our proposed system first undertakes healing at node-level. Failing to rectify system at node-level, network-level healing is undertaken. We have designed a system based on Xilinx Virtex-5 FPGAs and Cirronet DM2200 wireless mesh nodes to demonstrate autonomous wireless healing capability among networked node devices.
