Abstract: On the basis of classical graph coloring model,a cognitive radio spectrum allocation algorithm based on chaos quantum honey bee is presented.The algorithm is based on the theory of artificial colony,combining with the efficiency of quantum computing and the ergodicity of chaotic initialization to realize the spectrum allocation optimization problem.The simulation experiments show that compared with the color sensitive graph coloring algorithm,the spectrum allocation based on quantum-inspired genetic algorithm,and the spectrum allocation based on quantum-inspired bee colony optimization algorithm,the algorithm in this paper has good convergence and performances
