Abstract: | Spatial distance has a remarkable effect on the attended mode of a network embedded in a certain space. First, we investigate
how spatial restriction leads to information-information correlation that is strong, linear and positive in real networks.
We then construct a two-dimensional space, define the action radius R for nodes of networks, and propose a class of models that depend on spatial distance. Information correlation of the models
is consistent with that of real networks. The spatial distance plays a leading role in generating assortative mixing by degree,
while the generation of disassortative mixing relies on both the degree of preferential attachment and spatial restriction. |
