Abstract

The invention provides an unmanned aerial vehicle formation optimal information interaction topology generation method and apparatus. The method comprises the following steps: a communication network topology and a corresponding undirected weighed graph are obtained according to a formation pattern of a two dimensional lasting formation that needs to be formed by unmanned aerial vehicles, a two dimensional optimal rigid graph of the undirected weighed graph is calculated according to a two dimensional optimal rigid graph generation algorithm, a two dimensional optimal lasting graph is obtained according to the two dimensional optimal rigid graph and a two dimensional optimal lasting graph generation algorithm, and the two dimensional optimal lasting graph is an optimal information interaction topology for the formation. The apparatus provided in an embodiment of the invention can be implemented based on the above method. Via the method and the apparatus, formation communication cost of the two dimensional lasting formation can be minimized during formation pattern keeping processes.

Description

technical field [0001] The present invention relates to the field of communication technology, in particular to a method and device for generating an optimal information interaction topology of an unmanned aerial vehicle formation. Background technique [0002] During the take-off and cruising phase, all unmanned aerial vehicles (UAVs) usually exchange information through point-to-point communication links (communication links) to form a certain formation shape (formation shape or formation geometry), and maintain this formation formation to continue flying towards the target area . The communication link used is called the information exchange topology, communication topology, connection topology, information structure or information topology of the UAV formation. They are just Part of the set of all available communication links between UAVs. For a unified expression, the name "information exchange topology" is used below. At the same time, the collection of all availab...
