基于二维元胞自动机的网络模型刘 佳 张文铸 金德鹏 袁 坚 曾烈光 王耀希


摘 要:针对一维元胞自动机网络模型的转发过程随机化,二维模型缺乏拥塞特性分析的缺陷,提出了一种基于二维元胞自动机的网络模型。根据TCP/IP拥塞控制协议设计了元胞更新规则,并设置不同的元胞队列长度以增强网络的异构性。利用该模型仿真得到了拥塞相态下的节点负载、节点处理延时具有白噪声特性和1/f噪声特性。通过该模型观测到局部网络与整个网络负载特性的关系,表明该二维元胞自动机网络模型具有可扩展性,适用于大规模网络的行为建模研究。

  Abstract:Aiming to improve the shortcomings such as random forwarding and lacking analysis of congestion in one-dimensional and two-dimensional cellular automation model, this paper proposed a network model based on the two-dimensional cellular automaton. The transition rule of cells was designed in accordance with TCP/IP congestion control protocol, and the cellular in the model was with different queue length in order to enhance the heterogeneity of the network. The simulation results reveal that the traffic load of the node and the processing delay of the node are with characters of white noise and 1/f noise. The difference of the load characteristics between the local networks and the entire networks is also observed. It is shows that the model based on the two-dimensional cellular automaton is scalable and applicable for research on the behavior of large-scale networks. ......
