多QoS约束的组播路由技术是当前实现分布式网络多媒体的关键技术,蚁群算法是解决多QoS约束组播路由问题的一种启发式算法,但大多算法仍属于集中式算法.该文提出了一种基于蚁群优化的分布式QoS多播路由算法,并结合多播路由问题的特点对算法进行了改进.通过仿真实验讨论了该方法的性能,并与传统的蚁群算法对比,证实了其的有效性. Multicast routing technology with multiple QoS constraints is the key technology to realize multimedia in distributed network at present, and ant colony algorithm is a heuristic algorithm to solve the multicast routing problem with multiple QoS constraints, but most of the algorithms still belong to the centralized algorithm. A distributed QoS multicast routing algorithm based on ant colony optimization is proposed and the algorithm is improved by combining with the characteristics of multicast routing.The performance of this method is discussed by simulation and compared with the traditional ant colony algorithm Its effectiveness.
