QoS Multicast Routing Problem Based on Artificial Fish-Swarm Algorithm

Bandwidth-delay-constrained multicast routing problem is an NP-complete problem. In this paper, we propose a QoS multicast routing algorithm based on Artificial Fish Swarm optimization. Meeting with the Bandwidth-delay-constrained, the proposed algorithm can search the least-cost multicast routing tree quickly. Simulation results show that this algorithm has high reliability and good performance of global optimization, and suit for real-time, high-speed multimedia transmission network.
