In view of the end-to-end communication interruption problem of armored formations in complex battlefield environments, relay-assisted methods are often used to establish cooperative communications links, and the choice of relay is a key issue. In order to improve the communication coordination ability among formations, an optimal relay selection algorithm for armored formations based on wireless ultraviolet (UV) covert communication is proposed on the premise of decode-and-forward protocol, combined with the threshold decision idea. The algorithm combines the advantages of UV NLOS(non-line-of-sight) communication. The optimal relay selection is made for the formations according to the signal-to-noise ratio (SNR) threshold and channel characteristics selection strategy, and the bit error rate (BER) performance is analyzed under Gaussian noise model. The simulation results show that the optimal relay link can be obtained by selecting the appropriate cooperation threshold according to different SNR environments and relay number. Furthermore, adjusting the receiving and transmitting status of the relay, when the cooperative communications link changes dynamically, can effectively improve the communication quality of the cooperative relay link.
