Abstract: The fractal and self-similarity properties are revealed in many real complex networks. However, the classical information dimension of complex networks is not practical for real complex networks. In this paper, a new information dimension to characterize the dimension of complex networks is proposed. The difference of information for each box in the box-covering algorithm of complex networks is considered by this measure. The proposed method is applied to calculate the fractal dimensions of some real networks. Our results show that the proposed method is efficient for fractal dimension of complex networks.
