Abstract: With the purpose to solve the Multicast routing model efficiently,we combine clustering methods and multicast tree algorithms,a cluster-based multicast routing algorithm is proposed. The problem is tackled by ANN:A self-organising-map neural network has been used for clustering; Hopfield neural networks are used to construct a multicast tree,whose nodes are all of cluster-head. The algorithm is not only simple and characterized with its quick convergence,efficient and low maintenance costs of routing. Meanwhile,the efficiency of the method is supported by Simulation.
