Abstract: | Aimed at lowering the effect of `rich get richer' in scale-free
networks with the Barab\'{a}si and Albert model, this paper
proposes a new evolving mechanism, which
includes dividing and preference attachment for the growth of a
network. A broad scale characteristic which is independent of the
initial network topology is obtained with the proposed model. By
simulating, it is found that preferential attachment causes the
appearance of the scale-free characteristic,
while the dividing will decrease the power-law behaviour and
drive the evolution of broad scale networks. |
