Abstract

The invention discloses an unmanned aerial vehicle (UAV) network resource allocation method based on an improved longicorn beetle antennae search algorithm, a terminal of an unmanned aerial vehicle communication system is composed of a UAV pair (UAV), the method comprises the following steps: (1) initializing system parameters including a signal to interference plus noise ratio threshold value, power of a UAV transmitting terminal and other parameters; (2) representing a scheme of sharing channel resources by a user by using a position vector, and randomly generating an initial solution conforming to a constraint condition as a current position; (3) respectively corresponding positions of the left and right whiskers of the longhorn beetle at the current position are obtained; (4) solving the throughput of the current position of the system and the corresponding positions of the left and right sides in the UAV communication system, and updating the longhorn beetle position by taking a system throughput performance optimization index as an objective function; And (5) repeating the above steps until iteration is stopped, and carrying out reverse decoding on the coding space to obtainan optimal resource allocation scheme. The system throughput can be effectively improved, and the method is excellent in performance and easy to implement.

Description

technical field [0001] The invention relates to the field of unmanned aerial vehicle communication, in particular to a method for allocating resources of an unmanned aerial vehicle cooperative communication network based on an improved beetle beetle search algorithm. Background technique [0002] Unmanned Aerial Vehicle (UVA) is an aircraft operated by radio remote control equipment and automatic program control device. In recent years, with the promotion of drone projects, drones have been introduced into many applications in the world. Therefore, the scarcity of radio spectrum in UAV communication prompts us to consider improving spectrum resources. Bluetooth, WIFI and other communication modes need to go through complex manual pairing, and work in unlicensed spectrum, so the security of information transmission is insufficient. This problem can be overcome by using direct communication between UAVs, thus improving spectrum utilization. [0003] After decades of develop...
