AbstractIndustry 4.0 initiated the need of networking the factory automation and manufacturing facilities by forming industrial wireless networks. The industrial wireless networks transmit control packets having hard real time traffic with stringent deadline and reliability requirements. This paper presents a novel control panel approach that guarantees timely delivery of the control packets in a reliable industrial wireless network. Considering the wireless channel contention in these networks, the control panel aims at offering deterministic channel access time to each node in the network based on their relative message deadlines. A deterministic channel access algorithm is proposed in this paper to offer time guaranteed control packet delivery and a parameter, Pguarantee is developed to determine the probability of timely delivery of control packets before the deadline. The use of this proposed deterministic channel access algorithm in Industry 4.0 applications along with adaptive error control approach helps in supporting the timely and reliable delivery of the control packets. The performance of the proposed method is shown through detailed analytical and simulation experiment results in this paper.
