Media access control manner with QoS for control network
Lei Zhaoming, Sun Hexu, Liu Zuojun, Liang Tao · 2008
Control network takes responsibility for data communication in the networked control system (NCS), so the media access control of network is the key to guaranteeing the efficiency of the system. The paper presents a novel variable priority token passing data communication manner for the media access control in control network. The theoretical analysis, mathematical analysis and experiments are given on after the other. Comparison from experiments shows high efficiency and advantage of the presented manner than that of CSMA/CD and standard token-passing.
