Abstract

The invention discloses an unmanned aerial vehicle optimal speed scheduling method based on an actual model in wireless sensor network data acquisition. The method comprises three parts, namely scene information preprocessing, effective speed calculation of a "segment" and unmanned aerial vehicle flight speed setting. According to the invention, the sensor information is processed and the information of the "segment" is initialized; then, the effective speed of each "segment" according to parameters such as effective distance, effective time and the like is calculated; and finally, the obtained effective speeds is screened, and finally the optimal speed plan of the unmanned aerial vehicle is obtained.

Description

technical field [0001] The invention belongs to the field of wireless sensor network data acquisition research, in particular to an actual model-based optimal speed scheduling method for unmanned aerial vehicles in wireless sensor network data acquisition. Background technique [0002] Recently, UAV-based wireless communication technology has attracted great attention. The main advantage of this emerging technology is that UAVs can use their high mobility to establish a visual communication link with the ground, thereby alleviating signal jamming. One of the key applications is the collection of massive data in wireless sensor networks. In traditional WSN data collection, especially in remote, harsh terrain environments, static sensors must perform multi-hop transmission due to limited communication range. This means that some sensors need to transmit not only their own data, but also that of other sensors, causing these sensors to quickly drain their batteries and increas...
