An Energy Consumption Optimization For Multi-uav Data Transmission Based On Optimal Stopping Theory

With the increasing development of UAV technology,it has been widely used in all walks of life,enriching people's lives greatly.At the same time,the collaborative mode of multi-UAV is more efficient and smarter than the mode of single UAV,making it evolve each passing day.Currently,one of the most serious problems that multi-UAV collaborative implementation faced is the shortage of batteries.Therefore,it is urgent to find a way to reduce the energy consumption of multi-UAV when performing a synergistic task.The optimal stopping theory is a method in the field of economics and finance originally.In recent years,the optimal stopping theory has become the effective technology to solve the Internet difficulties.In this paper,the optimal stopping theory is applied to the selection of optimal UAV relay points.By selecting the satisfying conditions of relay UAS,the energy consumption of multi-UAV can be reduced when transferring data.Firstly,when performing a cooperative task,the architecture and data transmission protocol of multi-UAV are analyzed and summarized,which provides the basis of communication for establishing the data transmission model in this paper.And the current energy transfer algorithm in multi-UAV is introduced.Then,combining the features of real-time detection in source UAV,and adding the optimal stopping conditions in the original stopping method.Comparing the current value rates and total value with their forecast's,the weakness of single and unsuitable in the original stopping method is improved.To improve the stability,security and efficiency,the restrictions of multi-UAV select relay point are increased.In the experiment,the influence of different parameter values on the selection of the relay is studied.In addition,the ratio of optimal and the average energy consumption cost rate generated by the previous algorithm and the optimized algorithm are compared,and the advantage of optimization algorithm is shown.Finally,the application of the stopping theory in multi-UAV data transmission are discussed further.
