Probabilistic heuristics for disseminating information in networks

Subject Networking and Internet Architecture; Distributed, Parallel, and Cluster Computing ACM-class: C.2.2; F.2.2 | cs.NI cs.DC
AbstractWe study the problem of disseminating a piece of information through all the nodes of a network, given that it is known originally only to a single node. In the absence of any structural knowledge on the network other than the nodes’ neighborhoods, this problem is traditionally solved by flooding all the network’s edges. We analyze a recently introduced probabilistic algorithm for flooding and give an alternative probabilistic heuristic that can lead to some cost-effective improvements, like better trade-offs between the message and time complexities involved. We analyze the two algorithms both mathematically and by means of simulations, always within a random-graph framework and considering relevant node-degree distributions.
