Unmanned aerial vehicle deployment method for collecting forest fire prevention monitoring data

Abstract

The invention provides an unmanned aerial vehicle deployment method for collecting forest fire prevention monitoring data, and the method specifically comprises the following steps: (1), constructingan uplink communication system in which ground sensor nodes are connected to an aerial unmanned aerial vehicle base station, and the system comprises a plurality of rotor unmanned aerial vehicles andthe ground sensor nodes; (2) constructing an optimization problem aiming at maximizing the sum rate of data uploaded to the unmanned aerial vehicle base station by the ground sensor nodes; (3) constructing an optimization model based on the game theory, and the problem in the step (2) being modeled into a non-cooperative game model with the unmanned aerial vehicle as a participant; and (4) iteratively obtaining a deployment strategy of the unmanned aerial vehicle by adopting a distributed learning algorithm until the optimization problem in the step (2) is optimal, and determining the final position of the rotor unmanned aerial vehicle. On the premise of guaranteeing the QoS of the sensor nodes, the maximum sum rate between the unmanned aerial vehicle and the ground sensor nodes in the whole system is achieved.

Description

technical field [0001] The invention belongs to the technical field of wireless communication in the forest fire prevention monitoring scene, and in particular relates to an unmanned aerial vehicle deployment method for collecting forest fire prevention monitoring data. Background technique [0002] Fire prevention in forests and grasslands is a routine and important task of the forestry sector. Fires have brought immeasurable losses to the country and herdsmen. In the summer of 1997, the Indonesian forest fire known as the "disaster of the century" lasted for several months, burning more than 300,000 hectares of forests, causing direct economic losses of 12.5 million U.S. dollars, and as many as 20 million victims in Indonesia. disease, with more than 50,000 patients. In 2019, a total of 2,345 forest fires occurred in my country, and the affected forest area was as high as 13,505 hectares. A total of 25,000 national forest firefighting teams, 120,000 local professional for...
