Application-layer multicast scheme based on layered and clustering
Ren Qing-jie · Computer Engineering and Applications Journal · 2010
This paper proposes LCcast,a novel scheme based on NICE,which gives P2P application-layer for multicast.It us-es the hierarchical clustering structure,and makes the powerful leader nodes from all the clusters organized by the Chord in the result of extracting an implicit multicast tree easily.It uses the finger table defined in the Chord and the Dijkstra algo-rithm to establish the minimum delay multicast tree,and chooses a number of backup leader nodes in the cluster to form a stack in order to prevent the packet loss.Simulation results indicate that the scheme can improve the data transmission rate and reduce the control overhead and the load of the leader node.
