[Abstract]:In the real complex network, the network nodes will increase or decrease because of the change of the network topology, which will lead to the decrease of the transmission efficiency between the nodes of the network. In order to solve this problem, by analyzing the dynamic change of the nodes in the complex network, a dynamic transmission model for increasing the nodes of the network is proposed, and the influence of the changes of the network nodes on the transmission efficiency of the network is studied by using the data simulation of the real complex network. The results show that the initial size of the network changes with the dynamic increase of the network nodes. The transmission efficiency of the network is obviously affected by the dynamic increase of the nodes in the initial stage. As the nodes continue to increase, the transmission efficiency of the network tends to be stable. It shows stable network characteristics. In this process, the number of new nodes added to the complex network and the amount of information on the edge of the nodes maintain the information transmission of the network, which strengthens the transmission performance of the network, and makes the network have better overall control ability and effective node connection mode.
