Link-Blockage Model and AP-Placement Scheme for No-Blockage Link between AGV and AP in Logistics–Warehousing VLC Network

In this paper, the blockage problem of optical link between AGV (autonomous ground vehicles) and AP (access point) in logistics–warehousing VLC (visible light communication) network is analyzed. First, based on random geometric model, a link-blockage model proposed. Given position AGV, obstacle, state can be obtained through model. Then, an AP-placement scheme Under placement, AGVs any have reliable that not affected by obstacles. During movement will interrupted blockage. Finally, effectiveness demonstrated shadow method. outage probability data rate under different heights, spacings number obstacles are simulated. Simulation results show keep uninterrupted placement proposed paper.
