Abstract: In order to analyze the link performance of ultraviolet(UV)non line-of-sight(NLOS)communication network, based on the atmospheric single-scattered transmission model for the UV NLOS communication, two types of UV NLOS communication, i.e., all-direction transmitting and receiving, directed transmission and omni-direction receiving, were simulated in the chain and mesh topologies respectively. Then the network performance such as throughput, end-to-end delay, jitter etc were compared and analyzed through computer simulation. The results show that the performance of directed transmission and omni-direction receiving is more superior in the ultraviolet wireless optical network.
