The invention discloses a 
cost optimization unmanned aerial vehicle 
base station deployment method based on an improved 
genetic algorithm, and mainly solves the problem that the unmanned aerial vehicle 
base station deployment cost is difficult to optimize in the prior art. The realization method comprises the following steps: 1) establishing a ground 
wireless communication coverage model of the unmanned aerial vehicle 
base station; 2) calculating the maximum coverage 
radius and the optimal hovering height of the unmanned aerial vehicle base 
station in the unmanned aerial vehicle base 
station ground 
wireless communication coverage model scene; 3) deploying the unmanned aerial vehicle base stations at the optimal hovering height, enabling the deployment problem to be reduced from three-dimensional dimensionality to a two-dimensional plane, establishing an unmanned aerial vehicle base 
station deployment optimization model taking unmanned aerial vehicle base station deployment number optimization as a target, and solving the model to obtain an optimal 
chromosome; 4) converting the optimal 
chromosome into a corresponding unmanned aerial vehicle base station coordinate set to obtain an optimal unmanned aerial vehicle base station deployment scheme, reducing the complexity of the deployment problem, improving the solution accuracy, and being applicable to communication 
network deployment planning, temporary communication 
network construction and 
disaster area emergency communication.
