Embodiment

[0096] Example: A specific embodiment of the present invention is described as follows, the system simulation adopts Matlab software, and the solution of the optimization problem adopts CVX software package. The following embodiments examine the effectiveness of the data distribution-oriented joint optimization method for UAV flight trajectory and resource scheduling designed in the present invention.

[0097] In this example, if figure 2 As shown, the drone flies in the air and distributes data to the ground nodes. In the simulation, consider that K=5 ground nodes are randomly distributed in such as image 3 The size shown is within a square area of ​​1000m x 1000m. The flying height of the UAV is H=100m, and the initial and final positions of the flight are respectively set to q I = [0,0] and q F =[1000,1000]. Considering that the maximum transmission power of the UAV is P max =30dBm, the available channel bandwidth is B max = 1MHz, the energy consumption budget of...
