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.
