Abstract

The invention relates to a wireless sensor network data collection method based on an unmanned aerial vehicle group. An unmanned aerial vehicle accesses a sensor node to reduce the transmission energyconsumption of the sensor node; the unmanned aerial vehicles exchange data through wireless communication; and the unmanned aerial vehicles far away from the data aggregation point upload the data tothe data aggregation point through relays of other unmanned aerial vehicles, and each unmanned aerial vehicle plans an access path according to the position of the sensor node, so that the total number of sensor nodes accessed by all the unmanned aerial vehicles is as large as possible under the condition that the time delay requirement is met.

Description

technical field [0001] The invention relates to the technical field of wireless sensing, in particular to a method for collecting data of a wireless sensor network based on an unmanned aerial vehicle group. Background technique [0002] At present, wireless sensor networks have been widely used in environmental monitoring, military and other fields. Since sensor devices are generally powered by batteries, and the place where the wireless sensor network is deployed is generally inconvenient to reach, once the battery of the sensor device is exhausted, it means the death of the network node, causing the decline or even loss of the sensor network function. In wireless sensor networks, the energy consumption of sensor nodes is mainly concentrated in the wireless transmission of data. In addition, in practical applications, due to the obstruction of the terrain environment and the failure of some nodes, the network connectivity may be lost, so that the sensor network cannot cont...
