考虑无人机飞行时间的能耗与数据量联合优化
Joint Optimization of Energy Consumption and Data Volume Based on UAV Flight Time
摘要
Abstract
The use of UAV communication for data acquisition in wireless sensor networks is a valuable technology.For UAV data collection tasks in limited time,a joint optimization scheme considering system data volume,node transmission energy consumption and UAV flight energy consumption is presented.The decision space of this scheme includes UAV trajectory and transmission scheduling with high complexity.Since the joint optimization is an NP-hard problem,based on the dimensionality reduction of the decision space,the optimization process is divided into two steps:initial trajectory optimization and secondary trajectory optimization.For initial trajectory optimization,an optimization scheme based on greedy algorithm and tabu search algorithm is proposed to achieve node selection and obtain the initial trajectory of the UAV.For quadratic trajectory optimization,the discretization method is used to convert the original problem,and the successive convex approximation algorithm is used to optimize it,and an effective suboptimal solution is obtained.The simulation results show that the optimized scheme can increase the amount of data collected by the UAV and reduce the energy consumption of the UAV and the nodes while meeting the time constraints.关键词
