A Topology-Matching P2P Overlay Network Model Based on Hilbert Curve

Aiming at the unmatched topology problem between overlay network and physical network which result in inefficient routing,a new topology-matching P2P overlay network model is presented.Firstly,network nodes are clustered into K groups based on the network coordinates system Vivaldi,and selecting a leader node for each group.Then,using the proximity-aware nature of hilbert space filing curve,the K leader nodes are formed into ring topology.Finally a topology-matching Hilbert-Ring overlay network model is obtained.Simulating experiment shows that this model has the good performance,and it is effective in lowering the network delay and decreasing the network load.
