A Robust Algorithm for the Membership Management of Super-Peer Overlay

Peer-to-Peer technologies have been widely applied for multimedia applications. The super-peer based approach provides an efficient way to run applications by exploring nodes' heterogeneity. In P2P live video streaming, even though the number of stable nodes is small, they have significant impact on the performance of the network. Thus, the authors present a super-peer-based overlay design, where stable nodes are assigned as super-peers that organize client nodes. A Gossip-based Super-Peer Selection algorithm (GSPS) is proposed to identify the stable nodes to be chosen as super-peers and to manage the client nodes (namely the membership management).
