摘要

We present a network-level signaling mechanism for user access and service setup in light emitting diode (LED)-based visible light communication (VLC) networks and define the corresponding signaling messages.In this mechanism,lamp selection is an important step for realizing flexible user access and efficient resource allocation.Two basic selection schemes are proposed,and an enhanced bandwidth-based scheme is presented.Simulation results show the different advantages among these schemes.
