Real-time QoS multicasting routing optimization algorithm based on GA

The multicast routing problem with multiple QoS constraints in networks with uncertain parameters was discussed,and a network model and the optimizing function suitable for researching such real-time QoS multicast routing problem were described. A new QoS multicast tree selection algorithm based on Non-dominated Sorting technique of genetic algorithms was presented to simultaneously optimize multiple QoS parameters. The simulation results show that this approach has fast convergence speed and high reliability. It can meet the real-time requirement in multimedia communication networks.
