An Efficient Secure Framework for Hybrid Li-Fi/Wi-Fi Transmission Systems

Abstract

 In the era of the Internet of Things (IoT), data  on people, objects, and the environment flows are ever-increasing; light fidelity technology is one of the most creative but experimental futuristic networking techniques. To enhance the performance of complex narrowband Internet of Things (NB-IoT) systems, a recently developed hybrid network architecture that  consists of Wi-Fi and Light Fidelity (Li-Fi) is investigated in this article. Feasibility studies show that it can significantly improve the availability, dependability, productivity, and safety of systems , while drastically reducing latency and bandwidth costs. The experimental results show that, compared with existing models, the hybrid model can effectively support multiple large data  streams and also facilitate quick computing convergence. Simulation results demonstrate that 1) the performance of this scheme also outperforms traditional schemes in terms of throughput, speed,  packet drop ratio, jitter and coverage range. The benefits of the proposed algorithm and other widely used algorithms in practical applications are compared in the conclusion, while some further improvements are also suggested.
