AI Summary

To address the challenge of jointly optimizing energy efficiency and reliability in industrial field networks—where node failures or link degradation compromise both objectives—this paper proposes a lightweight, distributed path reconfiguration mechanism. The method uniquely integrates energy-aware routing with time-sensitive networking (TSN) real-time constraints, leveraging a hierarchical SDN control architecture to formulate an energy–latency joint metric model and design a low-overhead heuristic path recomputation algorithm. Experimental evaluation on representative industrial topologies demonstrates that the approach reduces average link energy consumption by 32.7%, maintains end-to-end latency violation rates below 0.15%, and cuts control-plane deployment overhead by 60%. This work establishes a scalable, dynamic reconfiguration paradigm for high-reliability, low-power industrial wireless networks.
