Broadcasting with random faults. (English) Zbl 0658.05068
A communication network can be modeled by a graph. The problem is to broadcast a message that originates from a given node to the remaining nodes as fast as possible, in the presence of random edge faults. It is shown that if the number of edge faults is at most proportional to the total number of edges, there are networks for which the broadcast can be done in time O(log n), with high probability, where n is the number of nodes in the graph.
