摘要

Visible light communication (VLC) can offload the traffic from existing radio frequency networks and provide illumination at the same time. In order to mitigate intercell interference and to support multiple users, this paper proposes a user-centric quality-of-experience (QoE) optimization scheduling scheme with multicolor light emitting diodes (LED) to improve illumination quality. We design a greedy algorithm to allocate lightwave bandwidths and search for the optimal access point versus user equipment (AP-UE) links dynamically according to the traffic load and locations of UEs. The simulation results show that the proposed scheme offers a guaranteed UEs' QoE and helps schedule more UEs while ensuring illumination quality at the same time.
