摘要 现有的路由算法一般只优化单个QoS目标,存在很大的局限性。提出了基于遗传算法的QoS组播路由多目标优化算法,在每次进化中搜索组播路由树的Pareto最优解集。仿真实验表明,该方法有很高的成功率,能在有限代内搜索到一组有效的供用户自由选择的组播路由树,克服了单目标优化的缺陷。 The existing routing algorithms usually optimize a single objective, which have some inherent drawbacks. A GAbased multi-objective optimization algorithm for QoS muhicast routing is presented, which search for the set of Pareto optimal solutions of muhicast routing trees. Simulation results show that this algorithm has a high success ratio, and can obtain a set of multicast trees in finite evolutionary generations, which the users can choose freely, and overcomes the drawbacks of single objective optimization.
