Abstract
This study proposes a novel scheme of spectrum management based on node degree. The spectrum resource is divided into multiple levels by the node degree, with which cognitive nodes select the suitable frequency from some spectrum layer. The nodes with greater degree can choose a frequency that closer to the predominant frequency. The supports of additional equipment and protocol redesign are not necessary for the rapid deployed applications by using this proposed scheme. Finally, the efficiency of proposed scheme is testified with experiments.
