Abstract

The invention provides an information interaction topology optimization method and a device for an unmanned aerial vehicle cooperative situation awareness network, and relates to the field of unmannedaerial vehicle communication. The method comprises the following steps: acquiring a collaborative situation awareness network of an unmanned aerial vehicle; obtaining a minimum spanning tree based onthe collaborative situation awareness network, and obtaining an undirected graph based on the minimum spanning tree; deleting the minimum spanning tree from the collaborative situation awareness network to obtain a communication network; acquiring a three-dimensional linear independent graph based on the undirected graph; and obtaining a three-dimensional rigid graph based on the three-dimensional linear irrelevant graph and the communication network, wherein the three-dimensional rigid graph is the information interaction topology of the unmanned aerial vehicle cooperative situation awareness network. According to the optimization method provided by the invention, the efficiency of cooperatively executing the situation awareness task by the unmanned aerial vehicle is improved.

Description

technical field [0001] The invention relates to the field of unmanned aerial vehicle communication technology, in particular to an information interaction topology optimization method and device for an unmanned aerial vehicle cooperative situational awareness network. Background technique [0002] An unmanned aerial vehicle (UAV) is a reusable aircraft that is unmanned, autonomously controlled by a vehicle-mounted or ground automatic flight system, and contains a power system. UAVs have a wide range of applications in both military and civilian fields by virtue of their advantages. However, the ability of a single UAV to perform situational awareness tasks is slightly insufficient. In order to improve the efficiency of performing situational awareness tasks, multiple UAVs are often used to form a collaborative situational awareness network, and a suitable one is selected on the basis of this network. information exchange topology to carry out information exchange to coordin...
