Research on multiple access nodes transmission strategy in wireless sensor networks based on UAV dynamic relay
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.
