Embodiment Construction

[0040] The technical solutions of the present invention will be further described below with reference to the accompanying drawings.

[0041] The UAV communication network uses UAVs as air base stations, and collects data from sensor nodes during flight through the communication equipment carried by them. Compared with the traditional ground network, the UAV base station communication can quickly establish the corresponding communication network and will not be affected by the ground road conditions. Aiming at such a UAV data acquisition system, the present invention proposes a method for optimizing sensor emission energy consumption of a multi-antenna UAV data acquisition system.

[0042] like figure 1As shown, in one embodiment, the multi-antenna UAV data acquisition system system is an uplink communication system composed of a UAV with M antennas and K sensor nodes; Within a limited time T, the UAV starts from the starting position, flies over the K nodes in sequence alon...

Abstract

The invention discloses a sensor transmission energy consumption optimization method of a multi-antenna unmanned aerial vehicle data acquisition system, which is suitable for the communication scenario of the Internet of Things. The data acquisition system includes a single multi-antenna drone and multiple sensors, and uses the single multi-antenna drone as an air base station to serve multiple ground sensor nodes. The method includes the following steps: according to the geographic location of the sensor node and the drone Position and air-to-ground wireless channel models, establish channel fading models and corresponding system models; establish optimization problems based on UAV flight time constraints, sensor node transmit power constraints, and link transmission rate constraints. The speed of the drone and the signal transmission power of the sensor node are used to minimize the maximum energy consumption of the sensor node; the optimization problem is solved to obtain the optimal speed of the UAV and the power distribution scheme of the sensor node. The invention can realize the minimization of energy consumption and prolong the endurance of the sensor node equipment.

Description

technical field [0001] The invention belongs to the technical field of wireless communication, in particular to a method for optimizing sensor transmission energy consumption of a multi-antenna unmanned aerial vehicle data acquisition system. Background technique [0002] At present, the formation and realization of communication network mainly rely on ground base stations or relays and other fixed communication equipment. Although these devices can provide relatively stable communication requirements, their immobile characteristics lead to certain limitations in deployment and high costs. In the IoT environment, energy efficiency, ultra-low latency, reliability, and high-speed uplink communication become major challenges. IoT devices are very limited by batteries and often cannot transmit over long distances due to their energy limitations. Drones are an effective means of addressing many of the challenges associated with IoT. At present, the research on using multi-ante...
