Multi-users network model and the corresponding networking scheme for indoor VLC systems.

Recently, the visible light communication (VLC) based on LEDs has attracted much attention. In order to realize multi-users indoor VLC system based on the hybrid full-duplex, we design a kind of illumination/communication terminal and present the corresponding network model in this paper. We propose a multi-access scheme, which can avoid the access collision and network congestion. Meanwhile, we present a method to establish the link between users and expound the routing strategy of information forwarding. Besides, we evaluate the network performance by numerical simulations in aspects of access collision probability, throughput, access time and link establishment time. The results show that the proposed multi-access scheme and routing strategy are feasible for indoor VLC system.
