Hierarchical and Ordered P2P Super-peer Topology Construction

Topology construction is one of the most essential problems in P2P network research.The current super-peer topology construction employs a fixed two-layer structure and an unordered approach based on the gossip-based paradigm,which not only restrains the system performance but also produces too many traffic loads and makes super-peer hotspot of the system.Meanwhile it brings about the higher cost and the security issue.The paper presented a hierarchical and ordered super-peer topology,called HOST,which established an adaptive hierarchy structure of super-peers according to the network scale and exploited an ordered algorithm to regulate peer joining and leaving.The simulation results and analysis show that HOST can effectively control the generation and load balancing of super-peers,and remarka-bly reduce the topology construction and repair cost.
