A Fuzzy Decision Based Intelligent QoS Multicast Routing Algorithm

Quality of Service supported multicast has attracted more attentions in the last few years and is regarded as an important communication mechanism for implementing real-time multimedia applications in Next Generation Internet. Considering the difficulty on exact measurement and complete expression of network parameters, an intelligent QoS multicast routing algorithm based on Mind Evolutionary Computation is presented with introduction of principle of fuzzy mathematics. The corresponding model and its mathematical description are introduced. Under inaccurate information of QoS parameters and users' flexible QoS constraints, the proposed algorithm tries to find the multicast tree with maximum reliability degree and user's QoS satisfaction degree. Simulation results have shown that the proposed algorithm provides an available approach to QoS Multicast routing in networks environment with uncertain parameters.
