The proposed algorithm uses inspiration from Harris Hawk Optimization and the Arithmetic Optimization Algorithm to improve position relocation problems, premature convergence, and the poor accuracy the existing techniques face. The HHAOA algorithm was evaluated on various benchmark functions and compared with other optimization algorithms, namely Arithmetic Optimization Algorithm, Moth Flame Optimization, Sine Cosine Algorithm, Grey Wolf Optimization, and Harris Hawk Optimization. The proposed algorithm was also applied to a real-world industrial wireless mesh network simulation and experimentation on the real-time pressure process control system. All the results demonstrate that the HHAOA algorithm outperforms different algorithms regarding mean, standard deviation, convergence speed, accuracy, and robustness and improves client router connectivity and network congestion with a 31.7 reduction in Wireless Mesh Network routers. In the real-time pressure process, the HHAOA optimized Fractional-order Predictive PI (FOPPI) Controller produced a robust and smoother control signal leading to minimal peak overshoot and an average of a 53.244 faster settling. Based on the results, the algorithm enhanced the efficiency and reliability of industrial wireless networks and real-time pressure process control systems, which are critical for industrial automation and control applications. © 2023 by the authors. %K Control systems; Industrial research; Mesh generation; MESH networking; Process control; Real time control; Routers; Wireless mesh networks (WMN), Arithmetic optimization algorithm; Fractional order; Fractional-order predictive PI; Harris hawk optimization; Industrial wireless; Industrial wireless mesh network; MeshNetworks; Node placement; Optimal node placement; Optimisations; Optimization algorithms; Predictive PI; Pressure process; Real-time control; Wireless mesh, Optimization, algorithm; animal; Falconiformes; reproducibility; wireless communication, Algorithms; Animals; Computer Communication Networks; Falconiformes; Reproducibility of Results; Surgical Mesh; Wireless Technology %V 23 %A P.A.M.
