1. A relay selection method for unmanned aerial vehicles in post disaster emergency scenarios in underground space, comprising following steps:
collecting a maximum rate, a minimum rate and an average rate of data transmission assisted by a D2D user through an unmanned aerial vehicle (UAV) based on a prediction range of the D2D user for the UAV, and obtaining a first uncertain preference order of the D2D user for the UAV and a second uncertain preference order of the UAV for the D2D user;
obtaining a preference strategy of the D2D user for the UAV based on the first uncertain preference order and the second uncertain preference order, and constructing a many-to-one bilateral matching model according to a many-to-one bilateral matching algorithm; and
exchanging and matching the UAVs matched by any two D2D users based on the many-to-one bilateral matching model, and obtaining a stable matching result of bilateral exchange.
