Effect of Long-distance Connections Selection Method on Object Lookup in P2P Network
In order to improve the performance and reduce the cost of object lookup,the small-world paradigm is brought into P2P network by constructing some long-distance connections.The long-distance connections selection method based on history is proposed in this paper,according to the target distribution of object lookup in real P2P network.Our method is compared with the other two methods of long-distance connections selection.Simulation results show that the object lookup hops of our method are much shorter than those of other methods with lower cost and better robustness.
