This paper introduces a hierarchical network generated by a random sequence based on BRV model, which is more in accordance with the properties of real networks that do not have strict self-similarity property. The encoding method is used to determine node neighbors and calculate the total path length of the network. Analytically and iteratively, the degree distribution and limit formula of the average path length of a class of networks are obtained.
Considering that many real networks do not have strict self-similarity property, compared with deterministic evolutionary fractal networks, networks with random sequence structure may be more in accordance with the properties of real networks. In this paper, we generate a hierarchical network by a random sequence based on BRV model. Using the encoding method, we present a way to judge whether two nodes are neighbors and calculate the total path length of the network. We get the degree distribution and limit formula of the average path length of a class of networks, which are obtained by analytical method and iterative calculation.
