Abstract
Graph coloring, which is at the heart of several problems arising in wireless ad hoc networks, concerns the problem of assigning colors to the nodes of a graph such that adjacent nodes do not share the same color. This paper deals with the problem of generating valid colorings in a distributed way, while minimizing the number of colors used. Examples of related problems in wireless ad hoc networks are TDMA slot assignment, wakeup scheduling, and data collection. The presented algorithm is inspired by the desynchronization observed in the context of the calling behaviour of male Japanese tree frogs. Experimental results indicate that the proposed algorithm is very competitive with current state-of-the-art approaches.
