Embodiment Construction

[0045] In order to make the technical means, creative features, goals and effects achieved by the present invention easy to understand, the present invention will be further described below in conjunction with specific embodiments.

[0046] Such as Figure 1-Figure 3 As shown, using UAVs as flying base stations to improve the capacity and coverage of existing wireless networks has attracted great attention in recent years. A key feature of drones is the ability to communicate line-of-sight with users, which could lead to improved coverage and speed. Not only that, UAV as a base station has the advantages of low cost and high operability. Due to their high flexibility and mobility, drones can quickly and efficiently deploy cellular networks and improve their quality of service. On the one hand, UAV-based aerial base stations can be deployed to improve the wireless capacity and coverage of temporary events or hotspots such as stadiums and outdoor events. On the other hand, th...

Abstract

The invention discloses an unmanned aerial vehicle safety communication method based on multi-user scheduling. The method is suitable for data transmission between a base station and users in an emergency scene. Network coverage is provided for users by using an unmanned aerial vehicle base station, and access users are selected through a multi-user scheduling criterion by taking maximization of security capacity as a target. According to the method, multi-user scheduling is carried out by jointly considering path loss and small-scale fading, so that the safety capacity of an unmanned aerial vehicle communication system is improved to the greatest extent, and the communication quality from the unmanned aerial vehicle to a user terminal is effectively guaranteed.

Description

technical field [0001] The invention relates to a method for secure communication of an unmanned aerial vehicle based on multi-user scheduling, and belongs to the technical field of wireless communication. Background technique [0002] Due to the low cost, easy operation and high flexibility of drones, their use in the field of communication is becoming more and more widespread. The UAV network has huge application scenarios, especially for information technology, which has important practical significance. Although there are more and more research investments on UAV networks, the security issues of UAV networks have not been fully resolved, mainly because in wireless communication, due to the inherent broadcast characteristics of wireless media, information is easily read without permission. Authorized recipient interception. With the increasing demand for secure communication in UAV networks, how to solve these problems to establish a secure UAV communication network is ...
