Enabling Scalable and Reliable IoT Communication using Fiber Optic Infrastructure

This research proposes a solution to the problems related to dependability, latency, capacity, and the existing wireless communication infrastructures which have been overwhelmed by the exponential growth of Internet of Things (IoT) devices. To address these issues, this dissertation proposes a communication architecture based on fiber optic cables aimed at fulfilling the scalability and performance requirements of large-scale IoT deployments. The proposed approach integrates Software Defined Networking (SDN), Dense Wavelength Division Multiplexing (DWDM), and Passive Optical Networks (PON), providing high-speed, low-latency communication free from interference. Using a simulation environment in MATLAB, different IoT wireless and fiber backed networks were evaluated on throughput, latency, packet loss, and other key performance metrics. The results indicate that fiber optics enable seamless-device connectivity, accommodating thousands of IoT devices and significantly enhancing network performance. The conclusions drawn are that fiber optic technologies offer a viable and readily deployable solution for scalable Internet of Things communications, which require high dependability.
