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.
