Embodiment Construction

[0048] In order to make the purpose, technical solution and advantages of the present invention more clear, the embodiments of the present invention will be described in detail below in conjunction with the accompanying drawings. It should be noted that, in the case of no conflict, the embodiments in the present application and the features in the embodiments can be combined arbitrarily with each other.

[0049] The steps shown in the flowcharts of the figures may be performed in a computer system, such as a set of computer-executable instructions. Also, although a logical order is shown in the flowcharts, in some cases the steps shown or described may be performed in an order different from that shown or described herein.

[0050] It has been explained in the above background technology that most of the current aviation cluster networks adopt the traditional distributed network architecture, but the rapid movement of drones will lead to frequent changes in the network topolog...

Abstract

The invention discloses an aviation cluster network routing method, which comprises the following steps of: 1, dynamically adjusting a time interval of sending link layer discovery protocol (LLDP) messages by software defined network controller nodes according to position information and motion information of aviation cluster network nodes; step 2, calculating a performance evaluation value of each link according to the bandwidth and the transmission delay of each link; and step 3, according to the performance evaluation value of each link, selecting an optimal routing path to carry out data forwarding. According to the technical scheme provided by the embodiment of the invention, the problem that the flexible combat requirement of the future aviation cluster network is difficult to meet due to the fact that the rapid movement of the unmanned aerial vehicle causes the frequent change of the network extension in the existing aviation cluster network is solved.

Description

technical field [0001] The invention relates to but not limited to the technical field of aviation wireless communication, in particular to an aviation cluster network routing method. Background technique [0002] With the development of drone technology, more and more unmanned aerial vehicles (UAV) are used in the air battlefield to complete various combat tasks, such as situational awareness, target surveillance, search, etc. Since it is difficult for a single UAV to complete the requirements of complex tasks, clustering and networking are the development trends of UAV technology. The aviation cluster network composed of multiple UAVs breaks through the limitation of a single UAV, and has the advantages of low cost and high efficiency. Its networking capabilities and network performance will have an important impact on future war models. Although the aviation cluster network has many advantages, its practical application still faces some technical challenges. [0003] Mo...
