In the wireless ultraviolet (UV) light communication network, the effective networking method suitable for it can further improve the network performance such as information transmission quality and network coverage. A novel networking method for wireless UV-optic cooperative communication is proposed. Based on the wireless UV-light cooperative network model, a network node cooperative communication strategy is designed. The amplification-forwarding and decoding-forwarding methods in the multi-relay environment are studied. The error rate, communication range, transmit power and network performance gain of the UV-optical cooperative network under different relay and forwarding methods are verified by the simulation results. The research results show that the multi-relay cooperative communication can effectively improve the performance of the wireless UV optical communication network. Under the condition of the same bit error rate, the communication range of the UV light cooperative network using amplification and forwarding and decoding and forwarding is obviously better than that of the non-cooperative network, and the required transmission power is lower. The decoding and forwarding method is better than the amplification and forwarding method, and the more the number of cooperative communication nodes, the greater the communication range of the wireless ultraviolet light cooperative communication network.
