The industrial internet of things is expected to attract significant investment to the industry. In this new environment, blockchain presents immediate potential in industrial IoT applications, offering several benefits to industrial cyber-physical systems. However, works in the blockchain literature target environments that do not meet the reality of the factory and do not assess the impact of the blockchain on industrial process requirements. Thus, this chapter presents an investigation of the evolution of industrial process automation systems and blockchain-based applications in the horizontal and vertical integration of the various systems in a supply chain and factories. In addition, through an investigation of experimental work, this work presents issues and challenges to be faced for the application of blockchain in industrial processes. Evaluations and discussions are mainly focused on aspects of real-time systems in machine-to-machine communication of industrial processes.

WIA-PA network is a kind of multi-hop wireless network, which is specially designed for industrial process automation control. It uses hybrid management pattern with star and mesh structure. Intra-cluster and inter-cluster communication is scheduled simultaneously based on TDMA as well as FDMA. In this paper, a real-time cluster resources scheduling strategy for WIA-PA networks is proposed and the specific algorithm is implemented by edge-coloring. Our algorithm combines with optimal routing mechanism and arranges the order of links reasonably, resulting in avoiding conflict and improving the original communication success rate. Furthermore, the algorithm makes full use of channel resources, which greatly reduces end-to-end delay. The performance analysis shows that our algorithm is close to optimal for WIA-PA networks. In addition, compared with RSCA algorithm, our algorithm has lower latency and higher network throughput.
