| 摘 要： | 针对无线工业控制网络(WICN)的实时性和可靠性要求,在分析了几种常见的无线局域网的MAC协议(MACA、MA-CAW和IEEE802.11)的不足后,提出了一种基于令牌控制的MAC协议.并且还详细介绍了该协议中的令牌恢复机制、优先级机制和数据帧确认机制,并利用离散事件仿真平台OMNeT 对该协议和CSMA/CA协议进行了仿真对比试验.仿真结果表明,该协议保证了信道接入的公平性,减少了数据传输时延,增强了数据传输的可靠性,适用于无线工业控制网络. |

| Abstract: | After the feature of industrial control networks is introduced,the shortage of some familiar WLAN(wireless local areanetwork) MAC(media access control) protocols such as MACA,MACAWand IEEE802.11 are analyzed,and a MAC protocol basedon token control is presented to suit the WICN(wireless industrial control network).Logical ring under wireless link is defined;tokenresume and data frame acknowledge mechanisms are particular introduced.Then a simulation trial is made to compare the protocol withthe CSMA/CA protocol by use of OMNeT concrete event simulation platform.The results demonstrate that the protocol ensures theimpartiality of channel medium access,reduces the transmitting delay of data and meets the instantaneity requirement of WICN. |
