Recently, it has been found that the degree distribution of a user network has a significant effect on the traffic carried by a telephone network. In this paper, we investigate the effect of user clustering on the telephone traffic based on computer simulations. Both uniform and scale-free user networks have been considered. In a uniform user network, it has been found that the carried traffic is not affected by the clustering. On the other hand, a scale-free user network with high clustering produces more carried traffic compared to one with smaller clustering because of the larger call arrival rate and the smaller call blocking rate.
