Analysis of GA in overlay-based NCS
遗传算法在Overlay-NCS中的应用研究

Because of random and uncertain delay, Internet can not guarantee QoS requirements of Internet-based remote Networked Control System (NCS), such as real-time performance, thus affecting the stability of NCS. This paper combined the data transmission characteristics of remote NCS, using Overlay Network to improve the basic network QoS services and genetic algorithm and simulated annealing to optimize Overlay Network costs. These strategies can guarantee the reliability of remote NCS. It was illustrated through the simulation experiments that the strategies in the paper can minimize Overlay Network total costs on the basis of meeting the delay requirements of the remote NCS. It was helpful to the deployment of the control system in the Internet.
