Abstract: The authors discuss briefly some properties of the BA model and point out that such model is insufficient to describe real networks for its relatively small clustering coefficient.Based on the BA model,and introducing  edge addition into network evolution,the authors propose a modified network model.Numerical simulation results indicate that in the modified model,the networks are scale-free,just as the networks in the BA model.In addition,the networks in such model are highly clustered.It is shown that the clustering coefficient C of network increases with the increase of edge-addition probability p in the modified model.In particular,when p=1,C is found to be 100 times higher in the modified model than that in the BA model with the same network-size.

Key words: complex networks, clustering, edge addition, scale-free
