【摘要】：在真实的复杂网络中,网络节点会因为网络拓扑结构的变化而增减,进而导致网络节点间传输效率降低.针对这一问题,通过分析复杂网络节点的动态变化,提出网络节点增加的动态传输模型,并利用真实复杂网络的数据模拟仿真,研究网络节点变化对网络传输效率的影响.结果表明:网络的初始大小会随网络节点的动态增加而变化,其传输效率受节点动态增加的影响在最初阶段表现明显,随着节点的继续增加,网络传输效率会趋于平稳,表现出稳定的网络特性.在这个过程中,复杂网络每次新加入节点的个数和节点边维持了网络信息传输的信息量,强化了网络传的输性能,使得网络具有较好的总体控制能力和有效的节点连接方式.
[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.
