网络效益最大化的认知无线电频谱分配算法
Cognitive Radio Spectrum Assignment Algorithm with Network Benefit Maximization
摘要
Abstract
Firstly introduce the graph coloring model of spectrum allocation in cognitive radio system. According to this model,design self-adptive crossover and mutation operator with the network benefit maximization as the goal. Based on it,Niche technology is introduced. Then cognitive radio spectrum assignment based on self-adaptive Niche genetic algorithm is proposed. Simulations are conducted to com-pare the proposed method with color sensitive graph coloring algorithm and classical genetic algorithm. Results show that the proposed method cannot easily trap into local optimum,and can find the optimal solutions after only several generations,what is more,it better opti-mizes network spectrum utilization. The proposed method greatly outperforms the color sensitive graph coloring algorithm and classical genetic algorithm.关键词
