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. 相似文献
