Graph coloring is a widely used technique for allocation of time and frequency slots to nodes, for forming clusters, for constructing independent sets and dominating sets on wireless ad hoc and sensor networks. A good coloring approach should produce low color count as possible. Besides, since the nodes of a wireless ad hoc and sensor network operate with limited bandwidth, energy and computing resources, the coloring should be computed with few message passing and computational steps. In this paper, the authors provide a performance evaluation of distributed synchronous greedy graph coloring algorithms on ad hoc and sensor networks. They provide both theoretical and practical evaluations of distributed largest first and the distributed version of Brelaz's algorithm.
