IoT-Driven Optical Sensor Networks for Smart Infrastructure Monitoring in Warehouses

The implementation of smart warehouses foundations the basis of modern logistics and supply chains that demand its effective and continuous monitoring to ensure the structural integrity, environmental factors, and security. The electromagnetic interference, lack of scalability and power consumption are some of the constraints that accompany traditional wireless monitoring systems. The Internet of Things (IoT)-based optical sensor network (OSN) model of monitoring infrastructure in realtime in warehouses are suggested in the paper to address the mentioned constraints. This system operates on distributed fiber Bragg grating (FBG) sensors, optical wireless communication (OWC) channel and internet of things (IoT) gateways to deliver low-latency and high-bandwidth data communication, as well as being immune to interference. A mathematical model is developed to estimate the attenuation and latency of power used when deploying one of the warehouses. The results of simulation confirm that the proposed OSN is a far superior option over the existing RF-based internet of things (IoT) networks in terms of latency, energy consumption, and scalability and can be used in more sophisticated applications, such as predictive maintenance and fire detection. The solution is highly secure as well as cost effective as far as tracking smart infrastructure is concerned.
