This paper proposes a distributed computing architecture using the P2P paradigm. Our proposal gathers the peers into markets according to their computational resources. Each market is arranged in an N-tree and the trees are linked by a Bruijn graph. The tree topology allows efficient searching of available resources in a specific market, while Bruijn provides good scalability as search complexity...
Many distributed hash tables (DHTs) resolve lookups in O(\log n) hops, where n is the number of nodes. One-hop DHTs give lower lookup latencies and lower lookup failure rates. However, it is hard to maintain large, wide-area one-hop topologies. We contribute aecast, a new topology dissemination algorithm for one-hop DHTs. It avoids expensive repair mechanisms and critical points of failure in existing...
In this paper we present a low cost fault-tolerant attitude determination system to a scientific satellite using COTS devices. We related our experience in developing the attitude determination system, where we combine proven fault tolerance techniques to protect the whole system composed only by COTS from the effects produced by transient faults. We detailed the failure cases and the detection, reconfiguration...
