Abstract

The invention belongs to the technical field of unmanned aerial vehicle ad hoc network communication, and discloses a relay selection method based on a track relationship in an unmanned aerial vehiclead hoc network, and an unmanned aerial vehicle, and the method comprises the steps: constructing an unmanned aerial vehicle ad hoc network model which comprises a source node, G ground base station nodes and N unmanned aerial vehicle nodes; constructing an information transmission scheme between communication nodes based on the unmanned aerial vehicle ad hoc network model, and defining track information; calculating a track direction and a transmission probability between the communication nodes based on an information transmission scheme between the communication nodes and the track information; establishing a relay selection method based on the track relationship based on the position relationship and the transmission probability between the communication nodes; and simulating the relayselection method based on the track relationship and the existing mechanism based on the same network parameters, and verifying the superiority of the method. Compared with an existing mechanism, themethod has better performance in the aspects of improving the information transmission success rate and reducing the transmission delay and the routing overhead.

Description

technical field

[0001] The invention belongs to the technical field of unmanned aerial vehicle ad hoc network communication, and in particular relates to a relay selection method based on a track relationship in an unmanned aerial vehicle ad hoc network and an unmanned aerial vehicle. Background technique

[0002] At present, the closest existing technology: UAV Ad Hoc Networks (Flying Ad Hoc Networks, FANETs), a special ad hoc network usually consists of a ground station (Ground Station, GS) and multiple UAVs in the sky ( Unmanned Aerial Vehicle, UAV) composition. In recent years, with the rapid development of sensors, embedded systems and GPS and other devices, UAV Ad Hoc Networks can be widely used in military and civilian fields.

[0003] Since drones are sparsely distributed in the air and fly at high speeds, a highly dynamic network topology results. Also, since power sources on drones are usually very limited, long-distance transmission should be avoided, as signal ...
