Unmanned aerial vehicle relay Internet of Vehicles secure transmission method based on non-orthogonal multiple access

Abstract

The invention discloses a unmanned aerial vehicle relay Internet of Vehicles secure transmission method based on non-orthogonal multiple access. The method comprises the following steps of: firstly, constructing a unmanned aerial vehicle relay Internet of Vehicles model based on non-orthogonal multiple access and comprising one base station, one unmanned aerial vehicle and V network edge vehicles; constructing a physical layer security model among the base station, the unmanned aerial vehicle and network edge vehicle nodes based on the unmanned aerial vehicle relay Internet of Vehicles model based on non-orthogonal multiple access; then, based on the unmanned aerial vehicle relay Internet of Vehicles model and the physical layer security model, constructing an unmanned aerial vehicle relay Internet of Vehicles secure information transmission target and optimization conditions; and finally, obtaining a solution through a golden section method and a graph theory based on the unmanned aerial vehicle relay Internet of Vehicles information secure transmission target and optimization conditions, and constructing an unmanned aerial vehicle relay Internet of Vehicles information secure transmission method. Compared with an existing mechanism, on the premise that the information transmission security is guaranteed, the total data transmission rate from the base station to the vehicle in the unmanned aerial vehicle relay Internet of vehicles can be increased.

Description

technical field [0001] The invention belongs to the technical field of unmanned aerial vehicles, and in particular relates to a safe transmission method for an unmanned aerial vehicle relay vehicle network. Background technique [0002] Unmanned aerial vehicles (UAVs) can be seen as potential enablers of future intelligent transportation systems providing different types of solutions. Initially, due to their high cost and limited technology, UAVs were usually used in the military field. Today, with the development of science, technology and economy, drones have been widely used in remote sensing, logistics, aerial photography and other fields. In particular, UAVs can be equipped with communication equipment to act as air relays, thereby improving the connectivity of vehicular adhoc networks (VANETs) and ensuring the quality of service of VANETs-related applications. Therefore, using UAVs as aerial relays is a promising heterogeneous wireless communication scheme that can e...
