Unmanned aerial vehicle relay selection method for underground space post-disaster emergency scene

Abstract

The invention discloses an unmanned aerial vehicle relay selection method for an underground space post-disaster emergency scene, and the method comprises the following steps: collecting the maximum rate, the minimum rate and the average rate of a D2D user for transmitting data through the assistance of an unmanned aerial vehicle based on the prediction range of the D2D user for the unmanned aerial vehicle, obtaining a first uncertain preference order of the D2D user for the unmanned aerial vehicle, and a second uncertain preference order of the unmanned aerial vehicle for the D2D user; based on the first uncertain preference order and the second uncertain preference order, obtaining a preference strategy of the D2D users for the unmanned aerial vehicles, performing matching according to a many-to-one bilateral matching algorithm, performing exchange matching on the unmanned aerial vehicles matched with any two D2D users, and obtaining a matching result with stable bilateral exchange; the algorithm is low in calculation complexity, the same relay unmanned aerial vehicle is allowed to cooperate with multiple pairs of D2D users in the same time slot for communication, the matching result is stable, and timely and effective communication of rescue workers as many as possible can be guaranteed.

Description

technical field [0001] The present application relates to the technical field of unmanned aerial vehicle relay matching, and in particular, relates to a method for selecting an unmanned aerial vehicle relay for post-disaster emergency scenarios in underground spaces. Background technique [0002] With the rapid development of the economy and the acceleration of the intelligentization of infrastructure, the development scale of underground spaces including mines, tunnels, subways, civil air defense projects, underground parking lots, etc. has continued to expand, and at the same time it has brought severe challenges to safety. Once a disaster occurs in the underground space, some or all of the basic sensing and communication facilities will be damaged, and the trapped people and rescuers will not be able to transmit information in real time. It will be difficult to effectively implement rescue operations, which will easily cause casualties and economic losses. Therefore, an e...

Problems solved by technology

In the post-disaster environment, the dynamic mobility of UAVs and D2D users may lead to the inability to obtain accurate preference lists, and thus the ineffective matching between D2D users and relay UAVs.
