Improved Acknowledgement Method based on WIA-PA

摘要

WIA-PA is a specification of wireless network communications used for industrial process automation. The acknowledgment method in WIA-PA protocol was studied in this paper and an improved method was proposed. The new method improves the possession ratio of valid data in network communication, meanwhile increases the communication safety and anti-jamming capacity. The simulation results show that this method can reduce the communication time of slot conversation communication, especially when there are large amounts of data need to interact between two sides, it can significantly improve the real-time of the industrial wireless network.
