摘　　要：提出一种利用无人机(Unmanned Aerial Vehicle,UAV)的动态中继传输策略来辅助WSN的多节点传输,传感器节点通过UAV将感知到的环境信息回传给远程基站。本研究旨在最大化回程链路接收端的总可实现速率,并构建了优化问题。通过块坐标下降算法和连续凸近似算法对该问题进行求解。仿真结果表明,该策略能有效提升回程链路的可实现速率,从而改善网络的整体性能。This paper introduces a dynamic relay transmission strategy using Unmanned Aerial Vehicles(UAV)to support multi-node transmission in WSN,where sensor nodes relay environmental data back to remote base stations via UAV.The objective is to maximize the aggregate achievable rate of the return link,for which an optimization problem is formulated.The problem is solved using the Block Coordinate Descent(BCD)algorithm and Successive Convex Approximation(SCA)technique.Simulation results demonstrate that this strategy significantly enhances the achievable rate of the return link,thereby improving the overall performance of the network.
