Embodiment Construction

[0038] It should be understood that the specific embodiments described here are only used to explain the present invention, not to limit the present invention.

[0039] refer to figure 1 , figure 1 It is a schematic structural diagram of the data relay system involved in the solution of the embodiment of the present invention.

[0040] Such as figure 1 As shown, the data relay system includes the existing ground network 01 and the UAV ad hoc network 02, the existing ground network 01 is similar to the function of data routing, and the UAV ad hoc network 02 includes multiple drone. The existing network 01 on the ground and the UAV ad hoc network 02 (each UAV in the UAV) can include: a processor 1001, such as a CPU, a communication bus 1002, a user interface 1003, a network interface 1004, and a memory 1005 . Wherein, the communication bus 1002 is used to realize connection and communication between these components. The user interface 1003 may include a display screen (Di...

Abstract

The invention discloses a multi-UAV and ground network efficient cooperative data relay method and system, wherein the existing network on the ground first traverses each UAV node in an UAV self-organizing network, and obtains the traversed environment awareness, connection time and data transmission time of the UAV node and the ground network; and then, the traversed fitness derivative between the current UAV node and the ground network is determined according to the environment awareness, the connection time and the data transmission time; finally, after the traversal of each UAV node in theUAV self-organizing network is finished, the fitness derivatives are compared with the preset fitness derivatives, and the node corresponding to the fitness derivative greater than the preset fitnessderivative is used as a relay node; the multi-UAV and ground network efficient cooperative data relay method and system can be protected from the influence of the change of the number of network nodes; the data relay of the ground network and the multi-UAV relay node is realized on the basis of not increasing the overall complexity of the network; and better tolerance and scalability are achieved.

Description

technical field [0001] The invention relates to the field of unmanned aerial vehicle communication technology, in particular to an efficient collaborative data relay method and system between multiple unmanned aerial vehicles and a ground network. Background technique [0002] The mutual cooperation between the UAV Ad Hoc Network and the ground network has greatly expanded the application of the existing network, and it is playing an increasingly important role in areas with imperfect network infrastructure, such as field military activities, anti-terrorism operations, and emergency rescue and disaster relief activities. information sharing. At present, the algorithms aimed at improving the collaboration among networks, such as ant colony optimization algorithm (ACO) and artificial bee colony optimization algorithm (ABC), can neither be used alone in complex heterogeneous mobile ad hoc networks, nor can they be implemented in cooperative networks. Based on the network frame...
