Abstract
By analyzing the spectrum allocation algorithms of graph coloring theory in the Cognitive Radio(CR) network,it is found that just a few in existing algorithms have considered whether the requirements of users are satisfied,which results in excessive allocation of resources to users with less demands. In order to solve this problem, the spectrum allocation priority functions are set based on user requirement algorithm,and the users whose needs have not been satisfied yet,are preferentially assigned. Then an improved algorithm is obtained. The simulation results show that the spectrum allocation algorithm based on user requirements can enhance the system channel efficiency,and improve the satisfaction of users.关键词
