A Searching Mechanism Based on Dynamic Topology Regularization in Gnutella Network

The searching mechanism of Gnutella in unstructured peer-to-peer network and its working principle are introduced. By analyzing its poor scalability problem, this paper proposes an improvement strategy based on dynamic topology regularization. The simulation results show that the strategy can effectively reduce the resource consumption of network and optimize the load-balancing among peers, and then improve the scalability of Gnutella network and the efficiency of resource search.
