摘　　要：为了分析紫外光非视距通信组网链路性能,采用单次散射大气信道传输模型,对紫外光非视距通信的全向发送全向接收和定向发送全向接收两类工作模式进行了理论分析,并在链状和网格状的拓扑结构下分别进行了计算机仿真实验,对比分析了两类工作模式下网络的吞吐量、时延、抖动率、丢包率等性能。结果表明,在紫外无线光Mesh网络的通信中,采用定向发送全向接收的接入方式能够使网络性能更优。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.
