With the requirements of users enhanced for wireless communication, the cooperative communication will become a development in tendency future. In this paper, a model based on complex networks with both preferential and random attachments is researched to solve an actual network-CCN (cooperative communication network). Firstly, the evolution of CCN is given by four steps with different probabilities. At the same time, the rate equations of nodes degree are presented to analyze the evolution of CCN. Secondly, the degree distribution is analyzed by calculating the rate equation and numerical simulation. Finally, the robustness of CCN is studied by numerical simulation with random attack and intentional attack to analyze the effects of degree distribution, average path length and average degree. The results of paper are more significant for building CCN to program the resource of communication.
