A method, device, and UAV node for network routing selection of unmanned aerial vehicles

Abstract

The embodiment of the present invention provides a UAV network route selection method, device and UAV node, which are applied in the field of wireless communication technology, including: when it is judged that the destination node is not within the communication range of the UAV node, the source node The space line between the UAV node and the destination node is used as the best virtual routing line, the virtual relay node on the line is determined, the reference node is selected from the virtual relay node, and the actual data sent by each neighbor node within the communication range of the UAV node is received. Position and motion state, determine the predicted position of the neighbor node in the current time period, use the predicted position to calculate the corresponding evaluation value, apply the corresponding evaluation value to the utility function, and determine the neighbor node with the smallest value of the corresponding utility function as the following One-hop relay node, and trigger the next-hop relay node to continue routing selection for the destination node. This solution solves the problem of unreliable network communication routing links of UAVs caused by the high-speed mobility of UAVs.

Description

technical field [0001] The present invention relates to the technical field of wireless communication, in particular to a method and device for selecting a UAV network route and a UAV node. Background technique [0002] Due to the ability of autonomous flight, rapid deployment and flexible networking, drones have great application potential in public and civil fields, such as emergency communications, environmental monitoring, border surveillance and monitoring, aerial photography, and survivors in disasters Search and rescue etc. Compared with single UAV system, multi-UAV system can complete the task more efficiently and economically. In a multi-UAV system, due to the rapid mobility of UAVs, it will lead to dynamic changes in the topology of the UAV network, making the routing of UAVs unstable. [0003] In the prior art, the UAV routing algorithm does not consider the impact of the UAV's fast mobility on the stability of the routing algorithm, which will undoubtedly lead ...
