摘　　要：为提高人工蜂群算法的开采能力和收敛速度,在人工蜂群算法中引入动态加速因子和种群自适应比例因子,得到一种新的动态加速种群自适应人工蜂群算法.将认知无线电TV频段频谱分配模型中的分配矩阵与动态加速种群自适应人工蜂群算法中的可行解相对应,分别以网络效益最大化和比例公平性为目标函数,实现了空闲TV频段频谱的合理分配.仿真结果表明,与其他算法相比,该算法能更好地实现网络效益的最大化以及用户之间的比例公平性.To improve the exploiting ability and speed the convergence of the artificial bee colony （ABC）, this paper proposes a dynamic acceleration population adaptive artificial bee colony （DA-PA-ABC） in which a dynamic acceleration operator and a population adaptive proportion operator are introduced. DA-PA-ABC is applied to solve the spectrum allocation problem of cognitive radio, in which feasible solutions correspond to the allocation matrix of the TV spectrum allocation model. Network benefit and fairness are taken as the objective function of the problem to achieve reasonable allocation of the idle TV spectrum. Simulation results show that, compared with other methods, spectrum allocation based on DA-PA-ABC can maximize network benefits and ensure fairness of users.
