Abstract

The invention provides a marine environment monitoring-oriented unmanned aerial vehicle and unmanned ship cooperative information returning method, which comprises the following steps of: uniformly expressing the influence of a channel condition in wireless transmission and a communication distance between an unmanned aerial vehicle and an unmanned ship on information return as the preference of the unmanned ship to a wireless channel allocated to the unmanned aerial vehicle; constructing a preference degree ranking table of the unmanned ship to the unmanned aerial vehicle; analyzing the transmission rate of information when the cooperative information of the unmanned ship and the unmanned aerial vehicle is returned, and maximizing the total throughput of the system through the joint optimization of the association relationship between the unmanned aerial vehicle and the unmanned ship and the transmitting power of the signal; and designing a heuristic algorithm based on a matching theory, determining a matching relationship between the unmanned aerial vehicle and the unmanned ship, and further determining the generation power of the unmanned ship and the unmanned aerial vehicle based on a convex optimization theory. The invention can effectively reduce the time complexity and calculation time of an algorithm, solves a problem that the connectivity of a communication link is weaker when the unmanned aerial vehicle serves as a mobile communication relay, and effectively monitors the marine environment.

Description

technical field [0001] The present invention relates to the technical field of wireless communication, in particular, to an information return method for the coordination of unmanned aerial vehicles and unmanned ships for marine environment monitoring. Background technique [0002] With the increasing business demands of the offshore wide-area Internet of Things, higher requirements are placed on wireless data transmission capabilities. At present, the main work of the marine Internet of Things includes hydrometeorological monitoring, maritime emergency communication system requirements, marine natural disaster early warning, hydrological survey, etc., and its application in the marine industry is becoming more and more extensive, such as sewage treatment, fuel leakage, and harmful metal emissions. Exceeding the standard has important applications. If the information transmission is not timely and accurate, it will cause serious damage to the marine environment, and may even...
