Probability-based Fault-tolerant Routing in Hypercubes

  author={Jehad Al-Sadi and Khaled Day and Mohamed Ould-Khaoua},
  journal={Comput. J.},
This paper describes a new fault-tolerant routing algorithm for the hypercube, using the concept of probability vectors. To compute these vectors, a node first determines its faulty set, which represents the set of all its neighbouring nodes that are faulty or unreachable due to faulty nodes or links. Each node then calculates a probability vector, where the kth element represents the probability that a destination node at distance k cannot be reached through a minimal path due to a faulty node…
