We design a mobile ad‐hoc network (MANET), where nodes are equipped with several multi‐beam adaptive array (MBAA) systems. Such devices provide a great advantage for both space and frequency freedom, and produce a much better network throughput than traditional systems based on single frequency, omnidirectional transmission. A license‐free bandwidth up to 7 GHz is available centered at 60 GHz. The problem to divide this bandwidth into several channels is described as frequency division issue in this paper. We have provided a possible solution for such a problem in our paper, formulated as a ( K , M ) list‐coloring problem of the associated graph. Major results are presented based on two different models for connection requests. In addition, a numerical test is performed to verify the analysis. Copyright © 2004 John Wiley & Sons, Ltd.
