Ground-air full-coverage power control and protocol design method based on centralized array antenna

Abstract

The invention discloses a ground-air full-coverage power control and protocol design method based on a centralized array antenna. According to the method, three-dimensional layouts and cruise trajectories of two unmanned aerial vehicles are optimized, the transmitting power of ground machine communication equipment is adjusted at the same time, two different convex approximation methods are combined, an original non-convex system energy efficiency optimization problem is converted into a convex problem, and optimal solution is achieved. The hovering height and the transmitting power of the unmanned aerial vehicle are reasonably set, the ground internet of things can firstly converge scene sensing data to a small access point coverage range, high-speed data uploading is achieved by fully utilizing the access bandwidth of a cellular network, and meanwhile energy consumption generated by large-range cruising of the unmanned aerial vehicle is avoided. According to the method, a space data compression process and an energy domain multi-antenna cooperative transmission process are creatively combined to realize high-energy-efficiency transmission, and an optimal parameter configuration scheme is found through experiments. The invention also provides a multi-unmanned aerial vehicle joint scheduling mechanism to guide the optimization process of the cruise trajectory of the unmanned aerial vehicle.
