A long-distance communication method for unmanned aerial vehicle group based on self-adaptation

Abstract

The invention discloses a long-distance communication method of a group of unmanned aerial vehicles based on self-adaptation. A UAV in that queue of the UAV group is selected as a relay node, and a moving instruction is sent to the relay node; the relay node receives and executes commands and monitors the RSSI strength with the predecessor UAV. When the RSSI strength is lower than the lower limitof the critical value, the relay node moves to the predecessor UAV. The relay node obtains the instruction to be transmitted from the predecessor UAV, judges whether the target UAV is itself or not, and if so, executes and feeds back the information; otherwise, the instruction is forwarded to the rear unmanned aerial vehicle; when the instruction to be transmitted is obtained from the rear unmanned aerial vehicle, the instruction is directly forwarded. The invention utilizes the multi-hop forwarding among relay UAV groups to prolong the control distance of the UAV groups and ensure the stability of the communication.

Description

technical field [0001] The invention relates to an adaptive long-distance communication method for unmanned aerial vehicle groups, which belongs to the technical field of unmanned aerial vehicle communication. Background technique [0002] At present, UAVs are widely used in many scenarios such as field inspections, target monitoring, and battlefield operations with their three-dimensional space exploration and expansion capabilities. UAV technologies and applications applied in different fields have attracted many academic circles. And the attention of the industry has invested a lot of manpower and material resources. After more than 20 years of development, UAV technology has been relatively mature. At present, most of the typical UAV application solutions are completed by a single aircraft. However, due to the limitation of the service capability of a single UAV, it is difficult to serve large-scale target areas at the same time. For example, when searching for a large...
