Embodiment Construction

[0013] A further detailed description will be given below in conjunction with the accompanying drawings and specific embodiments of the present invention.

[0014] figure 1 The UAV IoT system model in the present invention is shown. The present invention considers using the mobile UAV base station to collect data from the ground IoT nodes, and reasonably allocates the transmission channels and transmission power of the nodes. As shown in the figure, in the system, a UAV base station is deployed in the air, and M IoT nodes are randomly distributed throughout the area. Each IoT node has only one antenna, and there is data to be transmitted to the drone base station at all times. The UAV base station works on a pre-set flight trajectory, and it needs to allocate K orthogonal channels of the same width to ground IoT nodes for uplink data transmission in each time slot. In this example, the number of channels is less than the number of IoT nodes, that is, K<M. In each time slot,...

Abstract

The invention belongs to the technical field of wireless communication, and relates to a data collection method for an Internet of Things system based on an unmanned aerial vehicle. The invention uses the drone to collect data and control the uplink transmission process of the IoT node, optimizes the energy efficiency of the system to improve the battery life of the IoT system. In the solution of the present invention, the UAV device does not need to use real-time network information when making decisions, but extracts useful information from historical information and predicts the current network environment, thereby maximizing the long-term energy efficiency of all IoT nodes in the system .

Description

technical field [0001] The invention belongs to the technical field of wireless communication, and relates to a data collection method of an Internet of Things system based on an unmanned aerial vehicle. Background technique [0002] With the development of the Internet of Things (IoT) technology, the stock of the number of IoT devices and the amount of transmitted data have shown exponential growth, which puts forward higher requirements for the data collection of IoT devices. In addition, IoT devices are usually energy-constrained devices that cannot perform long-distance data transmission. Therefore, IoT systems urgently need an efficient, flexible and low-cost data collection method. Unmanned Aerial Vehicle (UAV) is seen as a viable solution. Unlike traditional data collection devices that are fixed on the ground, drones can fly in the air for dynamic deployment. This means that UAV equipment can quickly move to data hotspots during data collection, regardless of envi...
