摘要
研究基于QoS约束的组播树构建问题.采用种群数自适应遗传算法构建组播树,该算法可以对进化种群数进行宏观调控;同时,使用个体寿命限制个体的生存期,实现对种群数的微观调控.仿真结果证明了该算法的有效性.
This paper studies the muhicast tree construction problem based on QoS constraints. The muhicast trees are constructed by using population size adaptive genetic algorithm. The algorithm can control evolutionary popu- lation size at macro level. At the same time, in order to realize the micro-regulation of population size, it can restrict the individual survival period with individual life. Simulation results verify the effectiveness of this algorithm.
