Abstract: | Many realistic networks have community structures, namely, a network
consists of groups of nodes within which links are dense but among
which links are sparse. This paper proposes a growing network model
based on local processes, the addition of new nodes intra-community
and new links intra- or inter-community. Also, it utilizes the
preferential attachment for building connections determined by
nodes' strengths, which evolves dynamically during the growth of the
system. The resulting network reflects the intrinsic community
structure with generalized power-law distributions of nodes' degrees
and strengths. |
