Distributed Query Protocol on Heterogeneous P2P Overlay Networks

Considering the heterogeneity and physical location of nodes, this paper represents a layered mixed query routing protocol. It uses time-stamp to achieve the agreement of physical location and logical position, and introduces super-node to cope with load imbalance between nodes and performance bottlenecks. Simulation test on P2PSim shows that this solution is superior to other protocols, such as Kademlia, Chord, and Tapestry, on large-scale peer-to-peer (P2P) networks.
