| dc.description.abstract | With the demand for faster and secure communication technologies to make our lives better, innovative technologies like Li-Fi (Light Fidelity) are becoming increasingly popular. Li-Fi utilizes Light Emitting Diodes (LEDs) for accomplishing data transmission. This research concentrates around handover algorithms and performance evaluation of a Li-Fi network. Accordingly, the work is outlined in two parts. Firstly, this research work evaluates the performance of handover algorithms in Li-Fi network. Two handover algorithms are investigated namely, the closest-AP based algorithm (AP: Access Point) and maximum-channel-gain-based algorithm. Monte Carlo simulations using MATLAB tools are conducted to evaluate handover algorithms and show the impact of User Equipment (UE)’s rotation and movement on handover performance. Secondly, this research evaluates the performance of a Li-Fi network with multiple beams LEDs on moving UEs. The network performance is investigated in the case of the maximum channel gains. The simulated results show that when the beam angle is 30°, the Li-Fi system has the best performance in terms of channel gain (hence throughput) by considering its mean and standard deviation (SD) values. Thirdly, in this research I used concave mirror and the algorithm of cone to increase the range of Li-Fi. | en_US |
