Path-Fault-Tolerant Approximate Shortest-Path Trees
Let G = (V,E) be an n-nodes non-negatively real-weighted undirected graph. In this paper we show how to enrich a single-source shortest-path tree (SPT) of G with a sparse set of auxiliary edges selected from E, in order to create a structure which tolerates effectively a path failure in the SPT. This consists of a simultaneous fault of a set F of at most f adjacent edges along a shortest path e...
متن کاملMultiple-Edge-Fault-Tolerant Approximate Shortest-Path Trees
Let G be an n-node and m-edge positively real-weighted undirected graph. For any given integer f ≥ 1, we study the problem of designing a sparse f-edge-fault-tolerant (f -EFT) σ-approximate single-source shortest-path tree (σ-ASPT), namely a subgraph of G having as few edges as possible and which, following the failure of a set F of at most f edges in G, contains paths from a fixed source that ...
متن کاملFault Tolerant Approximate BFS Trees
A fault-tolerant structure for a network is required to continue functioning following the failure of some of the network’s edges or vertices. This paper addresses the problem of designing a fault-tolerant (α, β) approximate BFS tree (or FT-ABFS tree for short), namely, a subgraph H of the given network G such that subsequent to the failure of a single edge, the surviving part of H still contai...
متن کاملSparse Fault-Tolerant BFS Trees
A fault-tolerant structure for a network is required to continue functioning following the failure of some of the network’s edges or vertices. This paper considers breadth-first search (BFS) spanning trees, and addresses the problem of designing a sparse fault-tolerant BFS tree, or FT-BFS tree for short, namely, a sparse subgraph T of the given network G such that subsequent to the failure of a...
متن کاملApproximate Shortest Path Queries Using Voronoi Duals
We propose an approximation method to answer point-to-point shortest path queries in undirected edge-weighted graphs, based on random sampling and Voronoi duals. We compute a simplification of the graph by selecting nodes independently at random with probability p. Edges are generated as the Voronoi dual of the original graph, using the selected nodes as Voronoi sites. This overlay graph allows...
