Abstract: Gnutella is one of the basic protocols for P2P software. In this paper, a novel network model based on Gnutella is introduced. The mechanism of this network is based on resource occupancy and search activities of peers. As for the structure, the power-law exponent of in-degree gamma(in) approximate to 4.2, the length of the average shortest path < l > = 57.74, and the diameter of the network is 156; these topological properties of the proposed structure differ from known results.
