提出了一种基于改进蚁群算法的QoS组播路由优化求解方法。新算法采用精英策略进行信息素更新、转轮赌法进行路径选择和变化的信息素强度等方法进行改进。仿真结果表明改进的蚁群算法能有效满足各种业务的服务质量需求。
The QoS multicast routing optimization method based on improved ant colony algorithm is put forward. The improved algorithm adoptes elite strategy for updating pheromone, roulette wheel for path selection and changeable information strength. The simulation results show that the improved ant colony algorithm can effectively meet the business needs of the service quality.
