Abstract
In the field of emergency response,due to time sensitivity and resource constraints,it is particularly critical to explore the UAV-assisted edge computing technology to improve the efficiency of ground emergency response.Considering the energy limitation of UAV,this research is devoted to minimizing energy consumption by optimizing the UAV's task unloading decision,flying speed and hovering position.Facing the strong coupling and non-convexity of the optimization variables in the original problem,we use penalty function technology,successive convex approximation and block coordinate descent strategy to decompose the complex problem into several convex optimization subproblems that are easy to handle.In particular,when dealing with the second subproblem,we utilize the Lagrange multiplier method and the Karush-Kuhn-Tucker(KKT)condition to derive a closed-form solution for the optimal flight speed of the UAV.In addition,through a series of experimental analyses,we also determine the optimal configuration of the number of UAVs.Simulation results show that compared with the existing benchmark method,the proposed method can reduce energy consumption by up to 40％and improve energy efficiency significantly.This proves that through accurate task planning and algorithm optimization,the energy consumption of UAV clusters can be effectively reduced while ensuring the smooth completion of tasks.关键词
