A realistic model for complex networks with local interaction,self-organization and order

In this paper, a new mechanism for the emergence of scale-freedistribution is proposed. It is more realistic than the existingmechanism. Based on our mechanism, a model responsible for thescale-free distribution with an exponent in a range of 3-to-5 isgiven. Moreover, this model could also reproduce the exponentialdistribution that is discovered in some real networks. Finally, theanalytical result of the model is given and the simulation shows thevalidity of our result.
