    ABSTRACT: We propose a network model with a fixed number of nodes and links and with a dynamic which favors links between nodes differing in connectivity. We observe a phase transition and parameter regimes with degree distributions following power laws, P(k)∼k-γP(k)∼k-γ, with γγ ranging from 0.20.2 to 0.50.5, small-world properties, with a network diameter following D(N)∼logND(N)∼logN and relative high clustering, following C(N)∼1/NC(N)∼1/N and C(k)∼k-αC(k)∼k-α, with αα close to 3. We compare our results with data from real-world protein interaction networks.

    ABSTRACT: We propose a network model with a fixed number of nodes and links with a dynamics which favors links between nodes differing in connectivity. Parameter regimes where the degree distributions follow power-laws, P(k) ~ k^-gamma, high clustering following C(N) ~ 1/N and small-world properties, with a network diameter following D(N) ~ A+ B log N, are observed. Our model gives results comparable with real-world protein networks.
