为了改善紫外光(UV)点对点通信中传输距离有限、覆盖范围小的问题, 组建了UV自组织(Ad Hoc)网络。结合UV通信的信道特性, 提出了一种UV组网通信收发装置设计方案。基于该方案, 给出了UV Ad Hoc网络节点定位算法, 该算法利用节点间的通信距离和扇区信息求得节点间的相对位置。以无线Ad Hoc网络多播按需距离矢量路由协议为基础, 提出了一种UV空分复用Ad Hoc网络路由协议, 并对该路由协议进行了仿真, 给出了不同节点数和运动区域下的仿真结果。结果表明:在满足发包数、时延和丢包率等通信要求的前提下, 在一定运动区域内, 应选择较少的节点; 当节点数一定时, 应选择较小的运动区域。

The limited transmission distance and coverage of point-to-point ultraviolet (UV) communication can be improved with an UV self-organization (Ad Hoc) network. Combined with the channel characteristics of UV communication, a design scheme of UV network communication transceiver device is proposed. Based on this scheme, an UV Ad Hoc network node localization algorithm is proposed, which can obtain the relative position between the nodes with the communication distance and sector information between nodes. Based on the wireless Ad Hoc multicast on-demand distance-vector routing protocol, a routing protocol of UV space division multiplexing Ad Hoc network is proposed and simulated. The simulation results under different moving areas and numbers of nodes show that under the premise of meeting communication requirements such as number of message sent, delay and packet loss rate, fewer nodes should be chosen in a certain moving area, and when the number of nodes is constant, a small moving area should be selected.
