Multi-constrained QoS Multicast Routing Algorithm Based on Adaptive Ant Colony Algorithm

This paper unifies the characteristics of multiconstrained QoS multicast routing problem,by using an improved adaptive ant colony optimization algorithm to solve multicast routing problem.In real network communications,by considering the link utilization influence transforms bandwidth of link into cost problems.According to the cost of the way which ants choose to updating pheromone,increase the adaptability of pheromone updating,then improve convergence ability of algorithm.Cause the multicast routing algorithm in considering the QoS constraints of network on the basis of further conforms to actual network demands.
