Abstract

A b-coloring of a graph is a proper coloring where each color admits at least one node (called dominating node) adjacent to every other used color. Such a coloring gives a partitioning of the graph in clusters for which every cluster has a clusterhead (the dominating node) adjacent to each other cluster. Such a decomposition is very interesting for large distributed systems, networks,... In this paper we present a distributed algorithm to compute a b-coloring of a graph, and we propose an application for the routing in networks to illustrate our algorithm.
