摘　　要：WIA-PA是我国制定的用于过程自动化的工业无线网络协议标准,基于传统单信道和信道竞争的MAC协议不能满足工业无线网络对通信抗干扰、实时性和可靠性的较高要求。提出基于WIA-PA分簇网络的多信道TDMA MAC协议即TMCC-MAC。该协议改进了IEEE 802.15.4超帧结构,并主要研究了WIA-PA网络簇间通信信道和时隙分配问题。实验表明该协议同时具有低功耗、多信道和时分通信的优点,能较好地满足工业无线通信要求。The WIA-PA standard is developed for process automation in industrial wireless network by China.Traditional contention-based MAC layer protocols using a single channel can not meet the requirement of the high interference resistance,low-latency and high reliability in industrial network communication.A multi-channel TDMA MAC protocol based on WIA-PA clustering network called TMCC-MAC was proposed.This protocol improved the super-frame structure of the IEEE 802.15.4,and focused on the inter-cluster channels and time slots resource assignment.Experimental results show that the protocol has the advantage of low power,multiple channels and TDMA which plays a good performance in industrial network communication.
