A f-fault-tolerant (approximate) shortest path tree is a subgraph of the input graph G which contains a (approximate) shortest path tree in G−F for any faulty ...
Dec 5, 2024 · Our results are based on two different constructions. On one hand, we show how to augment (by adding a small number of edges) a fault-tolerant ...
Jul 2, 2014 · Abstract:The resiliency of a network is its ability to remain \emph{effectively} functioning also when any of its nodes or links fails.
In this paper we address this trade-off for the prominent case of the broadcasting routing scheme, and we build efficient (i.e., sparse and fast) fault-tolerant ...
