With the continuous development and progress of wireless communication technology, balancing and optimizing the signal-to-noise ratio (SNR) of wireless signals, two-way transmission in the face of external noise is a hot research issue. This paper is based on an amorphous flat air-to-ground wireless self-organizing network system as a research framework, on the basis of one-way relay beamforming, an SNR balance optimization solution for bidirectional trunk beams for this article is proposed, this makes the system when the system is facing external noise interference, its signal-to-noise ratio can still be in good state and have good balance and control ability so that the self-network node can achieve point-to-point long-distance transmission. The simulation results show that when the signal source or the resource node is used as the source node, although the power allocation strategy corresponding to each network node is different, the same optimum signal-to-noise ratio can be obtained as a whole; The experiment results show that can effectively and significantly increase the limit distance of signal communication transmission in wireless ad hoc networks, wireless signal transmission distance increased from the original 667 meters to 2200 meters, the wireless signal transmission distance is relatively increased by 229.835%. This paper provides a specific theoretical basis for subsequent further improvement of long-distance transmission from the network node.
