中文摘要本发明涉及工业无线网络技术,具体地说是一种基于信道模型的工厂自动化无线网络ARQ重传方法。本发明方法面向IEEE?802.11单跳BSS结构的星型网络,一方面降低了维护和管理的难度,提高了系统的灵活性,其采用TDMA机制支持大规模网络节点的重传数据在TDMA各时隙有序传输,满足了网络实时和可靠的要求。采用基于链路层信道模型动态预留重传时隙的方法,在保证了可靠性指标的同时,降低了重传通信资源分配所带来的时间和报文开销,提高了通信资源利用率。采用聚合NACK以及根据ID值分配资源的方法,显著降低了由传输ACK与资源分配信息带来的开销,实现了高效率、低开销以及易于实现等目标。

英文摘要The invention relates to the industrial wireless network technology, in particular to a channel model based factory automation wireless network ARQ retransmitting method. The method is oriented to a star network of an IEEE 802.11 single-hop BSS structure, reduces difficulty for maintenance and management, improves the system flexibility, and meets the network real-time and reliable requirements as the method adopts a TDMA mechanism to support ordered transmission for retransmission data of large-scale network nodes in each TDMA time slot. The dynamic retransmission time slot reserving method based on a link layer channel model is adopted to ensure the reliability index, reduce the time and message overhead due to distribution of the retransmission communication resource and improve the communication resource utilization rate. Aggregated NACK and a resource distribution method based on ID value are utilized to obviously reduce the overhead due to ACK transmission and resource distribution information, and achieve high efficiency, low overhead, high possibility of implementing and the like.
