摘要: Visible Light Communication (VLC) systems are becoming an effective means of wireless communication with the potential to provide dense and fast connectivity at low cost. In this paper, we consider a VLC-WiFi heterogeneous system and investigate dynamic resource allocation for a multi-user environment to maximize the downlink capacity. This work addresses the joint allocation problem of assigning users to Access points (APs) and scheduling them to resource blocks (RBs). An improved Proportional Fairness (PF) algorithm is proposed that takes into account the fairness of the hybrid heterogeneous VLC-WiFi network. Simulation results demonstrate that the proposed algorithm outperforms the traditional PF scheme, while the simulations have also illustrated the effectiveness of the proposed method.
