An Improved Hybrid P2P Control Model Based on Chord

Traditional hybrid P2P Botnet control model divides nodes into super nodes and client nodes, which made proper compromise between connectivity and aggregation, but it has serious “social-effect” problem. In this paper, an improved hybrid P2P control model (Shadow-Chord) based on chord is proposed, in which both super nodes and client nodes join a hidden structured Chord network in the usual, and they use backup communication channels to rejoin the network when all nodes in the routing table are unreachable. It is similar to construct a covert “shadow network” for hybrid P2P network. Simulation result shows that the Shadow-Chord model effectively lowers the clustering coefficient and solves the “social-effect” problem in traditional hybrid P2P network.
