Abstract

Internet networks are becoming more crowded every day due to the rapid development of modern life, which causes an increase in the demand for data circulating on the Internet. This creates several problems, such as buffer overflow of intermediate routers, and packet loss and time delay in packet delivery. The solution to these problems is to use a TCP/AQM system. The simulation results showed that there were differences in performance between the different controllers used. The proposed methods were simulated along with the required conditions in nonlinear systems to determine the best performance. It was found that the use of optimization Department of Electro-mechanical Engineering, University of Technology - Iraq tools (GA, FL) with a controller could achieve the best performance. The simulation results demonstrated the ability of the proposed methods to control the behavior of the system. The controller systems were simulated using Matlab/Simulink. The simulation results showed that the performance was better with the use of GA-PIDC compared to both FL-PIDC and PIDC in terms of stability time, height, and overrun ratio for a network with a variable queue that was targeted for comparison. The results were: the bypass ratio was 0, 3.3 and 21.8 the settling time was 0.002, 0.055, and 0.135; and the rise time was 0.001, 0.004 and 0.008 for GA-PIDC, FL-PIDC and PIDC, respectively. These results made it possible to compare the three control techniques.

基于Matlab的TCP/AQM网络性能增强仿真模型
由于现代生活的快速发展,互联网每天都变得越来越拥挤,这导致对互联网上流通的数据的需求增加。这会产生一些问题,例如中间路由器的缓冲区溢出,以及数据包传递中的数据包丢失和时间延迟。解决这些问题的方法是使用TCP/AQM系统。仿真结果表明,所使用的不同控制器在性能上存在差异。对所提出的方法以及非线性系统中所需的条件进行了模拟,以确定最佳性能。研究发现,使用伊拉克理工大学机电工程系优化工具(GA,FL)与控制器可以获得最佳性能。仿真结果证明了所提出的方法控制系统行为的能力。利用Matlab/Simulink对控制器系统进行了仿真。仿真结果表明,对于具有可变队列的网络,与FL-PIDC和PIDC相比,GA-PIDC的性能在稳定时间、高度和溢出率方面更好。结果表明:分流比分别为0、3.3和21.8,沉降时间分别为0.002、0.055和0.135;GA-PIDC、FL-PIDC和PIDC的上升时间分别为0.001、0.004和0.008。这些结果使得比较这三种控制技术成为可能。
