Performance Li-Fi Indoor Positioning Systems using RSS-Triangulation Method

This To solve the problems of low positioning accuracy and longtime consumption in terms of the indoor visible light 3D positioning system, which realizes many sensors or complex hybrid algorithm, it is generally believed that an indoor positioning system using Li-Fi (Light) Fidelity is one of the solutions Most cost-effective with light-emitting diode (LED). In our work, we designed a simulation data of positioning based on the 3D internal environment of the Li-Fi system. The proposed method was implemented on the Matlab system to simulate the sensor that calculates the location error within the triangulation method, as it is one of the methods of intrusion prevention that make the system achieve high resistance to interference and high accuracy in positioning to involved with the method of receiving signal strength (RSS) and under the influence of noise based on Li-Fi channel model for the user location and data simulation. In the simulation results for the proposed method, the power and accuracy of the RSS-triangulation method in calculating the position were determined as indicating that the average positioning error distance 7.40906 10
