摘　　要：紫外光自组网融合了紫外光通信背景辐射低、非视距(non-line-of-sight,NLOS)通信、局域保密性好、气候适应性强,以及自组网快速部署和高度灵活性等优点,成为紫外光通信实用化发展的关键。尽管目前紫外光自组网的研究已取得一定进展,但仍然存在物理层双工模式下节点自干扰、数据链路层媒体接入控制(media access control,MAC)协议的节点能耗高和同步困难、网络层网络连通性不佳和路由协议扩展性较差的问题。基于此,对紫外光自组网物理层、数据链路层及网络层的研究现状展开综述,并展望其未来发展方向。Ultraviolet Ad-Hoc network integrates the advantages of ultraviolet communication,including low background radiation,non-line-of-sight(NLOS)communication,high local security,and strong adaptability to various climatic conditions,along with the benefits of rapid deployment and high flexibility in Ad-Hoc network.These features make it a key technology for the practical development of ultraviolet communication.Although significant progress has been made in ultraviolet Ad-Hoc network research,several challenges remain.These include self-interference issues in the physical layer due to the full-duplex mode,node energy consumption and synchronization problems in the data link layer’s media access control(MAC)protocol,and poor network connectivity and scalability of routing protocols in the network layer.Based on this,the research status in the physical layer,data link layer,and network layer of ultraviolet Ad-Hoc network were reviewed,and the future development directions were also prospected.
