The goal is to reduce the handover overhead by appropriately assigning users to either the RF or the LiFi access point (AP). This project proposes a novel adaptive neruo- fuzzy logic (ANFIS)-based decision-making algorithm for VHO, which is capable of combining the merits of both schemes to achieve excellent handover, the proposed fuzzy logic based VHO decision-making algorithm has the potential to provide lower errors and better quality of service (QoS) to users in future wireless broadband communications. The desired results of execution and implementation were reached and error value is equal 3.85e-7.enVisible Light CommunicationThesis
