Abstract

With the integration of IoT into modern industry, operations have been redefined, enabling real-time data exchange, predictive maintenance, automation, and smart decision-making. Finally, this paper conducts a systematic literature review of 30 scholarly articles published from 2020 to 2025 to examine the applications, challenges, and advancements of IoT in the industrial environment. And they explore various areas, including security, scalability, interoperability, and supply chain optimization. To reaffirm a gap that already exists, the research offers an Integrated IoT Security and Efficiency Framework that is AI-driven threat detection backed by blockchain-based security, edge computing, and an adaptive supply chain. The study also proposes a structured taxonomy and a flowchart for the most common problems and their mitigation solutions. Security standards, protocol standardization, and robust security measures are a concern, while IoT has the potential to increase operational efficiency and sustainability. This research offers practical guidance to industry sectors seeking to run secure, scalable, and intelligent IoT in the context of an ever-changing Industry 4.0.

Keywords
