Energy-Efficient LiFi-Enabled Indoor Localization System for Smart Campus Environments

An important facilitator of smart campus services amid navigation assistance, asset tracking, occupancy analytics, and emergency management is indoor localization. The application of localization systems based on the radio frequencies is characterized by the problems of multi-pathing, congestion of the spectrum, and the consumption of even more energy in highdensity indoor areas. In this paper, a proposal is made to design an energy efficient LiFi based localization system with indoor coverage based on a current LED lighting system that offers high accuracy positions to users at very low power overhead cost. There is the development of a received signal strength (RSS)based localization model using the economic channel qualities, and an energy consumption model is created to measure system efficiency. Simulation results demonstrate sub-meter localization accuracy with up to 40% lower energy consumption compared to WiFi-based indoor positioning systems, making the proposed approach suitable for sustainable smart campus deployments.
