Research on Dynamic Spectrum Allocation Algorithm based on Channel Nodes

HE Shi-biao1,ZHANG Xin-chun1,SUN Jiang2(1.Chongqing Communication Institute,Chongqing 400035,China;2.Naval Aeronautical Engineering Academy,Yantai 264001,China)  
By taking the cognitive user's demand and system's computing cost into account,this paper discusses dynamic spectrum allocation algorithm taking channel nodes as coloring vertexs.An allocation model is established,the spectrum allocation algorithm based on graph theory is introduced,and the pro and con of the algorithm over already existed algorithms are analyzed.The simulation results show that the performance of the proposed algorithm is improved.
