Problems solved by technology

When a large number of nodes compete for the channel, the resulting conflicts will be very serious, directly affecting the communication performance of the network
Second, the high-speed movement of UAVs makes the nodes in the network frequently enter and exit the network
Frequent changes in network topology will cause serious loss of channel resources

Abstract

The invention discloses an unmanned aerial vehicle ad hoc network channel access control method based on flow prediction, and the unmanned aerial vehicle flight ad hoc network employs a time frame optimization method based on movement prediction and a channel resource distribution method based on movement prediction, and combines the advantages of saving channel resources and meeting the demands of safe transmission. And meanwhile, different QoS guarantees can be provided. According to the invention, the utilization rate of the channel can be greatly improved on the basis of ensuring safe transmission according to different scene requirements.

Description

technical field [0001] The present invention relates to the technical field of unmanned aerial vehicle ad hoc network architecture, in particular to a flow prediction-based channel access control method for an unmanned aerial vehicle ad hoc network. Background technique [0002] Flying adhoc Networks (FANETs) are becoming the main communication method for multiple unmanned systems due to their robustness, flexibility, and ease of deployment. Due to the limited capacity of a single UAV, it can no longer meet the complex task requirements. Multi-UAV cooperative operations have the advantages of high efficiency, scalability, and wide coverage, and can effectively meet increasingly complex mission requirements. It is the development trend of future UAV operations. [0003] However, while having many advantages over a single unmanned system, multiple unmanned systems still have their unique challenges in terms of communication. Communication is the key to ensure the normal oper...
